Cumulative inflation has permanently reset the cost of living. A data-driven investigation into housing, food, insurance, corporate margins, and the generational divide across seven countries.
The Price Tag of the New Normal
What 29% Cumulative Inflation Actually Means
Inflation rates have fallen. Prices have not. Since 2019, cumulative consumer price increases in the United States have reached 29.16% ✓ Established Fact [1] — meaning a dollar earned in 2019 now purchases roughly 77 cents worth of goods. The distinction between the rate of inflation and the price level is the single most important concept for understanding why everything still feels so expensive, even as central banks declare victory.
The confusion is understandable. When headline inflation falls from 9.1% to 2.4%, the natural assumption is that prices are coming down. They are not. Disinflation means prices are rising more slowly — not that they are declining. The cumulative effect of three years of elevated inflation has permanently reset the baseline cost of living across every major economy ✓ Established [1]. For prices to return to 2019 levels, the world would need sustained deflation — something no central bank is targeting and no economist is predicting.
In the United Kingdom, the picture is equally stark. Consumer prices increased 20.8% between May 2021 and May 2024 alone ✓ Established Fact [7]. Inflation peaked at 11.1% in October 2022 — a 41-year high — before easing over subsequent months. But easing inflation did not reverse the damage. UK private rents continued to rise at 8.7% annually through October 2024 [7], and food inflation remained at 4.9% in July 2025, well above the Bank of England's 2% target.
The European Union saw food and non-alcoholic beverages increase by 33.2% between 2016 and 2025 — the highest increase of any major consumer category [1]. In Japan, headline inflation has exceeded the Bank of Japan's 2% target for 41 consecutive months ✓ Established [11], a sustained deviation from decades of near-zero inflation that has fundamentally altered Japanese consumer behaviour. Germany, long Europe's anchor of price stability, saw real wages decline throughout 2024 as both rising inflation and slowing nominal wage growth compressed household purchasing power [5].
The political consequences have been immediate. Cost-of-living anxiety was a defining issue in the 2024 US presidential election, the 2024 UK general election, and the 2024 European Parliament elections. Incumbent parties across the democratic world discovered that voters do not distinguish between inflation rates and price levels — they feel the grocery bill, the rent cheque, and the insurance premium. The gap between macroeconomic data and household experience has become one of the defining political tensions of the decade.
US cumulative inflation reached 29.16% between 2019 and 2026 [1]. The UK saw 20.8% cumulative price increases in just three years (2021-2024) [7]. Central banks have successfully reduced the rate of inflation to near-target levels, but the price level itself is permanently elevated. No major economy is pursuing the sustained deflation that would be required to return prices to pre-pandemic baselines.
What makes this moment structurally different from previous inflationary episodes is the breadth of the increase. This is not a single commodity shock or a localised housing bubble. Food, housing, energy, insurance, healthcare, childcare, and transportation have all risen simultaneously, compounding the effect on household budgets in a way that no single statistic captures. The next seven sections examine where the money is actually going — category by category, country by country — and who is bearing the greatest burden.
Where the Money Goes
Housing, Food, Insurance, and the Categories That Never Came Down
Not all price increases are created equal. While headline inflation captures the average, the categories that consume the largest share of household budgets — housing, food, insurance, and energy — have risen faster, further, and with less prospect of reversal ✓ Established [3]. This is the anatomy of the squeeze.
Housing: the largest single cost. In the United States, 43.5 million households were cost-burdened in 2024, dedicating more than 30% of their income to housing ✓ Established Fact [3]. Among renters, the figure is worse: 50.3% of all US renter households — 23.2 million — now spend more than 30% of income on rent and utilities. In Florida, 60% of renters are cost-burdened; in Nevada 57%; in California 55% [3]. The IMF notes that housing is now less affordable than it was during the bubble that preceded the 2007-08 global financial crisis ◈ Strong Evidence [2].
The generational dimension is particularly acute. Sixty percent of OECD survey respondents aged 18-39 said they worried about housing affordability, compared with just 38% of those aged 55-64 [14]. In the United Kingdom, private rents rose 8.7% year-on-year through October 2024 [7], far outpacing wage growth. As of the first quarter of 2025, homeownership was unaffordable in 17 US states [3].
Food: the daily reminder. US food prices have risen 29.5% since December 2019 ✓ Established Fact [10]. Food-away-from-home (restaurants) rose 4.1% in 2024 and 3.8% in 2025 — consistently outpacing general inflation [10]. Perhaps most revealing is the farm-to-consumer breakdown: for every dollar spent on domestically produced food, only 20.1 cents reaches wholesale and retail trade establishments — the rest is absorbed by processing, transportation, packaging, and marketing [10].
Egg prices rose from $1.41 per dozen in 2019 to a peak of $6.22 in March 2025 — a 341% increase driven by the avian influenza outbreak that has affected over 157 million chickens since January 2024 [15]. The USDA invested $1 billion to combat the crisis. Prices eventually fell to approximately $2.50 by mid-2025 — still 77% above 2019 levels. The episode illustrates how concentrated supply chains amplify shocks: a biological event became an affordability crisis because the production system had no redundancy.
Insurance: the hidden inflation. Auto insurance premiums rose 16.5% in 2024, with the average annual premium reaching a record $2,101 in 2025 ✓ Established Fact [13]. The average auto claim now exceeds $13,000, driven by rising repair costs, more expensive vehicle technology, and higher labour rates [13]. Homeowners insurance rates surged 24% over the past two years, with some states seeing increases above 30% [13]. Health insurance premiums for employer-sponsored family coverage reached approximately $27,000 per year in 2025, up 5.6% from 2024, with a further 6.7% increase projected for 2026 [13].
Energy: volatile but structurally higher. US electricity prices averaged 18.05 cents per kWh in early 2026, up 5.4% year-on-year, driven by rising natural gas prices and unprecedented electricity demand growth [1]. In the UK, April 2025 was dubbed "Awful April" as energy bills rose alongside a 26.1% increase in water and sewage charges — the fastest such increase since the late 1980s [7]. European households in Germany, Ireland, and Italy faced among the highest electricity prices globally, with Irish households paying approximately $0.45 per kWh — more than double the US average [1].
Medical care: accelerating. US medical care prices rose 3.2% in 2025, with hospital and related services surging 6.7% — their largest December-to-December increase since 2010 ✓ Established [1]. The acceleration in healthcare costs is driven by specialty drugs — particularly GLP-1 medications — higher utilisation rates, and healthcare wage inflation. These costs compound through the insurance system, contributing to the premium increases documented above.
Childcare: the affordability barrier. Childcare costs rose approximately 22% between January 2020 and September 2024 [14]. In the United States, net childcare costs consume 23% of net household income for couples with two children — and 37% for single parents [14]. In the UK, childcare can consume up to 75% of a parent's income. By contrast, Germany's childcare costs represent just 1% of a couple's salary, and France 6% — demonstrating that policy choices, not market inevitability, determine the burden [14].
The Harvard Joint Center for Housing Studies found that 50.3% of all US renter households — 23.2 million — were cost-burdened in 2024, spending more than 30% of income on rent and utilities [3]. A further 21.6 million households of all tenure types were severely burdened, spending more than half their income on housing. The burden falls disproportionately on younger households, renters, and residents of Sun Belt states.
The compounding effect is what makes the current moment unprecedented. No single category increase would constitute a crisis on its own. But when housing, food, insurance, energy, healthcare, and childcare all rise simultaneously — and when wages fail to keep pace — the result is a structural compression of household budgets that leaves less for savings, less for investment, and less for the consumer spending that drives two-thirds of GDP.
The Profit Question
Record Margins in the Age of Consumer Squeeze
As consumers absorbed the largest cost-of-living increases in four decades, corporate profit margins reached historic highs. S&P 500 companies reported net margins of 16.4% in September 2025 — the highest level in over 15 years ✓ Established Fact [9]. The question of whether these margins contributed to inflation — or merely coincided with it — has become one of the most politically charged economic debates of the decade.
The numbers are not in dispute. The S&P 500's year-end average net profit margin reached 9.75% in 2024, compared with a historical average of 5.85% for the period 1989-2015 ✓ Established [9]. By Q3 2025, the Information Technology sector was reporting margins of 27.7%, Financials 20.2%, and Utilities 17.2% [9]. Analysts project even higher margins through 2026, with estimates of 12.8% to 13.7% for Q4 2025 through Q2 2026 [9].
The grocery sector tells a particularly instructive story. The FTC's March 2024 report on grocery supply chain disruptions found that food and beverage retailers' revenues were 6% above total costs in 2021, growing to 7% during the first three quarters of 2022 ◈ Strong Evidence [4]. The Commission noted that "some in the grocery retail industry seem to have used rising costs as an opportunity to further raise prices to increase their profits, which remain elevated today" [4].
Some in the grocery retail industry seem to have used rising costs as an opportunity to further raise prices to increase their profits, which remain elevated today.
— Federal Trade Commission, Grocery Supply Chain Report, March 2024Industry concentration amplifies pricing power. The FTC documented that just four companies — Walmart, Costco, Kroger, and Ahold Delhaize — control 65% of the US grocery market ✓ Established Fact [4]. This represents a doubling of concentration over 30 years: four firms accounted for roughly 30% of sales in 2019, compared with approximately 15% three decades earlier. The White House Council of Economic Advisers separately found that grocery and beverage retailers increased margins by nearly two percentage points since the eve of the pandemic — reaching the highest level in two decades [8].
The Groundwork Collaborative's analysis concluded that corporate profits drove over 50% of inflation during Q2-Q3 2023 ◈ Strong Evidence [8]. This finding is contested. Economists at the Federal Reserve Bank of San Francisco examined price markups during the 2021-2022 inflation surge and found that, across the economy, markups stayed "essentially flat" since the recovery — concluding that "fluctuations in markups were not a main driver of the post-pandemic surge in inflation" [9].
The resolution may lie in sector specificity. Economy-wide averages can mask significant variation. While aggregate markups remained relatively stable, specific sectors — particularly food retail, energy, insurance, and pharmaceuticals — appear to have expanded margins during and after the inflationary surge. The FTC's sector-specific findings are harder to dismiss than aggregate macroeconomic data, precisely because they examine the industries where consumers most acutely feel price increases.
A pattern emerges across multiple sectors: costs rose, companies raised prices; costs fell, companies did not lower prices proportionally. The result is a "margin ratchet" — a one-directional mechanism where supply shocks become permanent price increases. The S&P 500's net margin of 9.75% in 2024 versus the 1989-2015 average of 5.85% [9] suggests this ratchet has been operating for years — but the post-pandemic inflation surge accelerated it dramatically.
The political framing of "greedflation" — while reductive — captures a real phenomenon: in concentrated markets with inelastic demand, firms can raise prices beyond cost increases without losing significant market share. The evidence suggests this happened most clearly in food retail, insurance, and healthcare — precisely the categories where consumers have the fewest alternatives and the least price sensitivity, because they cannot simply stop eating, insuring their cars, or seeking medical treatment.
What is less debatable is the distributional consequence. Whether or not corporate margins caused inflation, the simultaneous occurrence of record profit margins and declining real wages represents a transfer of purchasing power from labour to capital. The income share flowing to corporate profits versus wages has shifted measurably since 2020 — and the inflationary period accelerated that shift [6].
The Shrinking Package, the Growing Bill
How Less Became More Expensive
Beyond headline price increases, a subtler mechanism has been at work. Shrinkflation — reducing product sizes while maintaining or increasing prices — has become a widespread strategy across the consumer goods industry, effectively raising per-unit costs while keeping shelf prices superficially stable ✓ Established Fact [8].
The scale of shrinkflation is now quantifiable. Research indicates that shrinkflation drove between 3.3% and 10.3% of price inflation among selected national grocery brands between Q1 2019 and Q3 2023 [8]. By 2025, the practice had intensified: some major brands reduced product sizes by over 30% without reducing prices, with shrinkflation averaging 14.8% among selected national grocery brands [8]. The consumer is paying the same — or more — for measurably less product.
Consumer awareness has caught up. Seventy-five percent of Americans report noticing shrinkflation at their grocery store ✓ Established [8]. Among those who have noticed, 81% have taken some form of action — switching brands, buying store-label alternatives, or reducing purchases altogether. Perhaps most significantly, 48% of American shoppers have abandoned a brand entirely due to shrinkflation [8].
The mechanism is economically rational but socially corrosive. By reducing package sizes rather than raising shelf prices, manufacturers exploit a well-documented cognitive bias: consumers are far more sensitive to price changes than to quantity changes. A bag of crisps that shrinks from 150g to 130g while remaining at £1.50 registers less sharply than the same bag rising to £1.75 — even though the per-gram cost increase is comparable. This is not a secret; it is a documented pricing strategy taught in business schools and implemented by packaging engineers.
The practice operates in a regulatory grey zone. While some jurisdictions require unit pricing (price per gram, per litre), enforcement is inconsistent and consumer attention to unit prices is limited. France introduced stricter shrinkflation disclosure requirements in 2024, requiring retailers to label products that have been downsized — one of the first regulatory responses to the practice. In the United States, no federal regulation specifically addresses shrinkflation, though the FTC has flagged it as a concern in its broader examination of grocery pricing practices [4].
When official inflation statistics measure price changes but fail to fully account for quantity reductions, the true cost of living is understated. A consumer who pays the same price for 14.8% less product has experienced a 14.8% real price increase that may not appear in CPI calculations. The gap between measured inflation and experienced inflation is partly explained by this mechanism — and it helps explain why consumer sentiment has diverged so sharply from official inflation data.
The food value chain illustrates the structural imbalance. For every dollar a US consumer spends on domestically produced food, a combined 20.1 cents goes to wholesale (6.3 cents) and retail (13.8 cents) trade establishments ✓ Established Fact [10]. The remaining 79.9 cents is absorbed by processing, packaging, transportation, marketing, and food service. When farm-gate prices fall — as they have for many commodities — the savings are absorbed along the supply chain rather than passed through to consumers. The result is a one-way valve: commodity price increases flow through to retail; commodity price decreases do not.
The broader pattern is one of opacity. Between shrinkflation, complex supply chains, and concentrated market power, the relationship between input costs and consumer prices has become increasingly opaque. Consumers can see that prices are higher; they cannot easily determine whether those increases reflect genuine cost pressures or margin expansion. This information asymmetry is itself a structural advantage for producers — and a structural disadvantage for the household budget.
Seven Countries, One Crisis
A Global Comparison of Purchasing Power Erosion
The cost-of-living squeeze is not an American phenomenon. From Tokyo to Toronto, Berlin to Brisbane, households across the advanced economies are experiencing the same structural compression — driven by the same forces but filtered through different policy frameworks, labour markets, and housing systems ✓ Established [5].
United States: Cumulative inflation of 29.16% since 2019 [1]. Food prices up 29.5% since December 2019 [10]. Auto insurance at record $2,101/year [13]. Hospital services inflation at 6.7%, the highest since 2010 [1]. Childcare consumes 23% of couple's net income, 37% for single parents [14]. The US has the most expensive healthcare system among advanced economies and one of the least affordable childcare systems in the OECD.
United Kingdom: Prices up 20.8% in just three years (2021-2024) [7]. Inflation peaked at 11.1% in October 2022. Private rents up 8.7% year-on-year [7]. Food inflation 4.9% in July 2025. Water and sewage bills surged 26.1% in April 2025 — the fastest increase since the late 1980s [7]. In November 2025, 61% of adults reported their cost of living had increased from the previous month, with 95% of those citing food prices and 68% citing energy bills [7]. Childcare can consume up to 75% of a parent's income.
Japan: A unique case. After decades of near-zero inflation, Japan's headline rate has exceeded the BOJ's 2% target for 41 consecutive months ✓ Established Fact [11]. Real wages have fallen every month in 2025 [11]. Despite the highest wage increases in over three decades — a 5.1% average in the 2024 spring wage offensive — nominal gains have been consistently outpaced by inflation. Among G7 countries, only Japan and Italy have seen real wages remain essentially flat since 1990 [11]. Japanese food inflation reached 3.5% in mid-2025 — the second highest in the G7 after the UK.
Real wages are now growing in virtually all OECD countries. However, they remain below the levels seen in early 2021 — just before the post-pandemic inflation surge — in around two thirds of them.
— OECD Wage Bulletin, March 2025Germany: Europe's largest economy has been particularly affected. Real wage growth declined throughout 2024 due to both rising inflation and slowing nominal wage growth [5]. German real wages remained approximately 3 percentage points below pre-pandemic levels by end of 2024 [5]. German households face among the highest electricity prices in the world — approximately $0.40 per kWh — driven by the Energiewende transition costs and taxes that constitute 30-50% of the final bill. One notable bright spot: childcare costs represent just 1% of a couple's salary, among the lowest in the OECD [14].
France: A relative outlier. France is one of the few OECD countries where real wage growth increased in 2024, driven primarily by falling inflation rather than accelerating wage growth [5]. French real wages remained less than 1.5 percentage points below pre-pandemic levels by end of 2024 — a smaller gap than most European peers. Childcare costs at 6% of a couple's salary reflect France's longstanding public investment in early childhood infrastructure. France also introduced stricter shrinkflation labelling requirements in 2024 — one of the first regulatory responses globally. However, food prices remain a sore point, with French households experiencing similar grocery inflation to their European neighbours.
Australia: Housing affordability plunged sharply, with the Demographia International Housing Affordability report ranking Australian cities among the least affordable globally [2]. Childcare costs are among the highest in the OECD. Energy prices have been driven upward by the transition away from coal and rising gas export prices. The combination of housing, childcare, and energy costs has made Australia's cost-of-living crisis particularly acute for families in major cities.
Canada: Housing affordability has deteriorated more sharply than in most peer economies. The IMF documents that Canadian affordability indices fell dramatically from 2021 to 2024, comparable to the US decline [2]. Real wage growth remained stable but insufficient to offset cumulative price increases. The cost-of-living crisis became a defining political issue, contributing to a dramatic shift in polling for the governing Liberal Party.
The cross-country comparison reveals an important pattern: while the severity varies, no advanced economy has escaped the squeeze. Countries with stronger social safety nets (France, Germany) have cushioned the impact through subsidised childcare, regulated rents, and minimum wage policies. Countries with more market-oriented approaches (US, UK, Australia) have left households more exposed to price increases in essential categories. The policy choices are not about preventing inflation — they are about determining who bears the cost.
The Generation Tax
Why Everything Costs More When You Are Under 35
The cost-of-living crisis does not affect all demographics equally. For adults under 35 — Millennials and Generation Z — the compounding effect of rising housing costs, stagnant entry-level wages, and student debt has created what amounts to a generational tax: a systematic erosion of purchasing power that is reshaping life trajectories ◈ Strong Evidence [12].
The numbers are stark. In 2005, Millennials could rent a one-bedroom apartment for approximately $759 per month, representing about 23% of a graduate's monthly salary. By 2025, Generation Z faces average rents between $1,650 and $1,671 — roughly 30% of the median graduate's monthly income ✓ Established Fact [12]. Across almost every US state, fewer than half of people under 35 own a home [12].
Starting salaries have risen in nominal terms — from approximately $39,000 in 2005 to around $65,700 in 2025 — but this represents only a roughly 12% real increase when adjusted for inflation [12]. Meanwhile, the average cost of a new vehicle rose 112% from $23,000 to $49,000 over the same period ✓ Established [12]. Public transit fares nearly doubled from $70 to $130 per month. Student loan repayments are 41% higher in inflation-adjusted terms than they were in 2005 [12].
The average new light vehicle cost approximately $23,000 in 2005; by 2025, that figure reached nearly $49,000 [12]. Starting salaries for college graduates rose from $39,000 to $65,700 over the same period — a 68% nominal increase but only 12% in real terms after adjusting for inflation. The divergence between essential costs and wage growth is the arithmetic core of the generational affordability crisis.
The behavioural consequences are measurable. One in three Gen Z adults worries about making rent or mortgage payments on time [12]. Many in their twenties and early thirties are delaying marriage, children, and even pet ownership because they cannot afford space. The concept of homeownership — long central to the social contract in English-speaking countries — is increasingly viewed as aspirational rather than achievable without inheritance or family support.
The OECD data confirms the generational dimension. Sixty percent of respondents aged 18-39 across OECD countries reported worry about housing affordability, compared with 38% of those aged 55-64 ✓ Established [14]. The gap was greatest in Ireland, Canada, and the United States — countries where housing has become most financialised and where institutional investors have entered the single-family rental market at scale.
| Risk | Severity | Assessment |
|---|---|---|
| Housing Affordability Collapse | Fewer than half of under-35s own homes in almost every US state. Rents consume 30% of graduate income vs 23% a generation ago. Without structural intervention, homeownership will become inheritance-dependent. | |
| Real Wage Stagnation | Entry-level real wages rose only 12% since 2005 while essential costs rose 60-112%. The gap between wage growth and cost growth is widening, not narrowing. | |
| Delayed Household Formation | Marriage, fertility, and homeownership rates declining among under-35s across all advanced economies. Demographic consequences will compound over decades through reduced consumption, lower birth rates, and smaller tax bases. | |
| Student Debt Drag | Average monthly repayment 41% higher in real terms than 2005, reducing disposable income and delaying savings, investment, and consumer spending among the most productive demographic cohort. | |
| Political Disillusionment | Cost-of-living anxiety is driving political realignment among younger voters. Trust in institutions that failed to prevent or adequately respond to the affordability crisis is declining measurably across OECD countries. |
The compounding effect is what distinguishes this from a cyclical downturn. Higher rents leave less for savings. Less savings means longer paths to homeownership. Longer renting periods mean more total spending on housing over a lifetime. Student debt reduces investment capacity during the years when compound growth matters most. Each factor reinforces the others, creating a self-perpetuating cycle that policy interventions — targeted at individual symptoms rather than structural causes — have thus far failed to break.
The intergenerational dimension adds a political charge. Older homeowners have benefited from the same asset price inflation that has priced younger buyers out. Property owners who purchased before 2020 have seen substantial wealth gains — in many cases, their homes have appreciated more in five years than their incomes grew in twenty. The result is a transfer of future purchasing power from young renters to older owners that operates through the housing market rather than through tax policy — making it largely invisible in political discourse despite its profound distributional consequences.
The Structural Debate
What Economists Agree On, Dispute, and Refuse to Say
The causes of the cost-of-living crisis are not as contested as political discourse suggests. There is broad consensus on the mechanics — but genuine disagreement on the relative weight of each factor, and a conspicuous silence on questions that would require uncomfortable policy conclusions ⚖ Contested.
What economists broadly agree on: The initial inflationary surge was triggered by the collision of massive fiscal and monetary stimulus with pandemic-disrupted supply chains. Energy price shocks from the Ukraine conflict amplified and prolonged the surge. Central bank rate hikes were necessary and largely effective at reducing the inflation rate. The cumulative price level increase will not reverse without sustained deflation that no policymaker is pursuing [5].
What they dispute: The role of corporate profits in sustaining inflation once supply-side pressures eased. The Groundwork Collaborative's finding that corporate profits drove over 50% of inflation in Q2-Q3 2023 [8] is met by the Federal Reserve Bank of San Francisco's conclusion that markups stayed "essentially flat" [9]. The disagreement is partly methodological — aggregate data versus sector-specific analysis — and partly ideological, reflecting different priors about market power and competitive dynamics.
The Market Correction View
Annual rates have returned to near-target levels (2-3%) across most advanced economies. The monetary tightening cycle worked as intended.
Real wages are growing in virtually all OECD countries. The labour market remains historically tight, giving workers bargaining power.
Nearshoring and diversification are reducing vulnerability to future shocks. 40% of US companies plan North American supply chain relocation by 2026.
Record margins attract new entrants and intensify competition. Consumer brand-switching (48% abandoning brands over shrinkflation) creates market pressure.
Every post-war inflationary episode was followed by a period of real wage catch-up. The current recovery is proceeding along historical norms.
The Structural Decline View
29% cumulative increase since 2019 will never reverse. Falling inflation rates mask a permanent reset in the cost of living.
Two-thirds of OECD countries have not recovered pre-surge purchasing power. Japan and Italy have been flat since 1990.
Four firms control 65% of US grocery. Market power in food, insurance, and healthcare allows prices to rise faster than costs — with no competitive correction in sight.
The IMF says housing is less affordable than pre-2008. Institutional investors, Airbnb, and financialisation have created a permanent affordability gap.
Under-35s face 112% higher vehicle costs, 30% rent burden (vs 23%), and 41% higher real student debt — with no prospect of catching up to prior generations' wealth trajectories.
What they refuse to say: Several conclusions follow logically from the evidence but remain largely absent from mainstream economic commentary. First, that the distinction between "inflation" and "price level" — while technically precise — is functionally irrelevant to households whose budgets are permanently compressed. Telling a family paying 29% more for groceries that "inflation is back to 2.5%" is accurate but unhelpful. Second, that housing affordability in major markets cannot be restored without either massive increases in supply, significant declines in asset prices, or both — and that either path creates losers among current homeowners who constitute the majority of voters. Third, that the cost-of-living crisis is, in part, a redistribution of income from consumers to shareholders — and that addressing it requires engaging with questions about market power, corporate taxation, and the share of national income flowing to capital versus labour.
When a central banker says inflation is at 2.5%, they are measuring the rate of change. When a consumer says everything is more expensive, they are measuring the level. Both are correct. The disconnect between macroeconomic data and household experience is not a communication failure — it is a measurement mismatch. Inflation statistics are designed for monetary policy; they were never intended to capture the lived experience of cumulative price shock. The political consequences of this mismatch have been severe: voters in multiple countries have punished incumbents not because the data was wrong, but because the data answered the wrong question.
The supply chain restructuring debate adds another layer of uncertainty. Proponents of nearshoring argue that relocating production to North America will reduce logistics costs and geopolitical risk. A 2025 Deloitte study found that 40% of US companies plan to relocate at least part of their supply chains to North America by 2026 [4]. But nearshoring itself carries costs: Mexican labour is only 20-30% cheaper than Chinese labour, capital investment in new facilities is substantial, and tariff policies create additional cost pressures that are invariably passed to consumers.
The most honest assessment is that the cost-of-living crisis results from a confluence of factors — pandemic stimulus, supply disruption, energy shock, market concentration, and policy choices — none of which alone is sufficient to explain the phenomenon, and all of which interact in ways that resist simple narratives. The "greedflation" framing captures something real about corporate pricing behaviour but oversimplifies the mechanisms. The "transitory inflation" framing was technically correct about the rate but catastrophically wrong about the level. The truth lies in the compounding interaction of these forces — and the structural advantages they confer on those who own assets, control markets, and set prices.
What the Evidence Tells Us
The Architecture of Permanent Affordability Decline
The evidence assembled across this report points to a structural conclusion: the cost-of-living increases that began in 2021 are not a cycle to be waited out but a permanent reset in the baseline cost of existence across the advanced economies ◈ Strong Evidence [5]. Understanding the architecture of this decline is a prerequisite for any effective response.
The mechanism operates through five reinforcing channels. First, cumulative price inflation: 29% in the US, 21% in the UK, and comparable levels across the OECD — none of which will reverse [1] [7]. Second, market concentration: four firms control 65% of the US grocery market, concentrated insurance markets set record premiums, and pharmaceutical pricing remains opaque [4]. Third, the margin ratchet: S&P 500 margins at 9.75% versus a historical average of 5.85% suggest costs are no longer the binding constraint on prices [9]. Fourth, housing financialisation: the transformation of housing from a consumption good into an investment asset has decoupled prices from local incomes [2]. Fifth, the wage-price disconnect: real wages remain below 2021 levels in two-thirds of OECD countries, meaning the cost increase has been absorbed by households, not shared with employers [5].
Cumulative price increases of 20-30% across the advanced economies are permanent. Central banks have successfully reduced the rate of inflation but are not targeting deflation. Corporate profit margins remain historically elevated [9]. Housing affordability has not improved despite rate cuts. Real wages in two-thirds of OECD countries remain below pre-surge levels [5]. The policy toolkit being deployed — interest rate adjustments, targeted subsidies, minimum wage increases — addresses symptoms rather than the structural drivers of affordability decline.
The cross-country evidence is instructive. France and Germany, with strong public investment in childcare (1-6% of couple's income versus 23-37% in the US), demonstrate that policy choices can substantially alter the burden [14]. France's shrinkflation labelling requirements show that transparency regulation is feasible. The UK's experience illustrates the consequences of inadequate social buffers: 61% of adults reporting monthly cost increases, with 95% citing food and 68% citing energy [7]. Japan's case demonstrates that even unprecedented wage increases (5.1%) can be rendered meaningless by persistent inflation that outpaces nominal gains [11].
The generational dimension may prove the most consequential long-term effect. The compounding burden on under-35s — 112% higher vehicle costs, 30% rent-to-income ratios versus 23%, 41% higher real student debt payments [12] — is not a temporary squeeze but a structural shift in intergenerational wealth distribution. The consequences will unfold over decades through delayed household formation, reduced fertility rates, lower savings, and diminished consumer spending capacity. These are not predictions; they are already measurable trends.
The 29% cumulative price increase since 2019 is a fact. The question is distributional: who absorbs it? The evidence suggests the burden has fallen disproportionately on renters, younger workers, and lower-income households — precisely those with the least capacity to absorb it. Corporate margins have widened. Asset owners have seen wealth gains. The cost-of-living crisis is, at its core, a redistribution event — and the political systems of the advanced democracies have not yet developed a framework for acknowledging or addressing that reality.
The policy implications are uncomfortable. Addressing market concentration requires antitrust enforcement that creates corporate opposition. Restoring housing affordability requires either massive construction programmes or price declines that threaten existing homeowner wealth. Rebalancing the wage-profit share requires labour market interventions that the business community resists. Funding social infrastructure — childcare, healthcare, public transport — requires taxation that voters nominally oppose even as they demand the services.
The most consequential finding is the permanence. Previous inflationary episodes in the post-war era were typically followed by periods of real wage catch-up that eventually restored purchasing power. The structural factors operating today — market concentration, housing financialisation, globalised supply chains, and the political constraints on redistributive policy — make equivalent catch-up less likely. The 29% is not a temporary deviation from a normal to which the economy will return. It is the new normal. The question for policymakers is no longer how to bring prices down — it is how to build a society that functions at permanently higher price levels without leaving the youngest and poorest behind.
The evidence does not support fatalism. Countries that have invested in social infrastructure, regulated concentrated markets, and maintained strong minimum wage policies have demonstrably cushioned the impact on households. The crisis is not the result of immutable economic forces — it is the product of specific policy choices, market structures, and distributional frameworks that can, in principle, be redesigned. Whether they will be is not an economic question. It is a political one.
