Housing
The affordability crisis that has reshaped politics in most developed countries. The wealth-concentration mechanism inside it. The reasons it is so hard to fix.

A note on framing. Housing is one of the most personally consequential topics on this site and one of the most politically charged. The trade-offs are real, the politics is hard, and the data is more useful than the slogans on either side - so the page below walks through what is actually true, what has changed, and what reforms have been tried, worked, or failed.
The new normal of unaffordability
Across much of the developed world, the cost of buying a home has risen far faster than incomes over the last 30 years. In a number of major cities the price-to-income ratio has tripled or more. The pattern is consistent across countries with very different politics: the United States, the United Kingdom, Canada, Australia, Ireland, the Netherlands, Sweden, South Korea, parts of Germany, parts of Spain. The same shift, with local variations.
In the United States, the median existing single-family home cost 4.7 times the median household income in 2025, down from a record 5.0 in 2022 but far above the 1990s average of 3.2 (Harvard's Joint Center for Housing Studies). In San Jose, Los Angeles, San Francisco and Vancouver the ratio is 9-11 in the 2026 Demographia survey of 2025 data. Sydney is at about 14, and Hong Kong, at 14.1, has topped the survey for 16 years.
Renting tells the same story differently. Rent-to-income ratios have risen across the developed world. The traditional rule of thumb that housing should consume about a third of income has been replaced by a reality where 40-50% is common in major cities and 60% or more is not unusual for households at the lower end of the income distribution. The Department of Housing and Urban Development in the United States classifies any household paying more than 30% of income on housing as "cost-burdened"; a record 22.7 million US renter households (49%) met that definition in 2024. Rent growth has since stalled: US apartment asking rents were 0.5% lower in early 2026 than a year before, though 29% above 2020.
The consequences of this go well beyond housing. Family formation has been pushed later because young couples cannot afford homes they want to start families in. Geographic mobility has fallen because moving for a better job often means losing access to a desirable housing market. Saving is harder because more income goes to housing. Generational wealth gaps have widened sharply because older homeowners have benefited from rising prices while younger households have not been able to enter the market. None of these is a trivial second-order effect; together they are reshaping how a generation is living its adult life.
Why housing decoupled from wages
Five forces working in roughly the same direction explain most of the shift, and they have largely not reversed.
Land-use restrictions tightened. The post-1970s wave of zoning, environmental review, historic preservation, and neighborhood-protection regulations across most developed countries made it much harder to build new housing in the places where demand was highest. Single-family-only zoning in much of urban America. Strict height limits in most European cities. Lengthy approval processes everywhere. The supply response that would historically have answered rising prices was weakened.
Interest rates fell for forty years. The average US 30-year mortgage rate fell from 18.6% in 1981 to 2.65% in 2021, with similar falls elsewhere. Lower rates mean larger mortgages can be afforded on the same income, which lifts what buyers can pay, which lifts prices. How much this explains is debated: Bank of England research credits falling rates with all of the rise in UK prices relative to incomes in 1985-2018; Edward Glaeser and colleagues credit them with a fifth of the 1996-2006 US boom. Rates rose sharply from 2022 and stood at 7.03% in September 2026, yet US prices were still up 1.5% on a year earlier in June, partly because owners locked into cheap mortgages are reluctant to sell.
Tax and subsidy systems favored owning. Mortgage interest deductions, capital-gains exclusions on primary residences, lower property taxes on owner-occupied homes, and government support for mortgage lending all subsidized housing demand. Each of these had reasonable individual justifications. Together they amplified the price effects of rising demand and falling supply.
Cities became more economically concentrated. Productive economic activity has clustered in fewer cities than it did in the 1970s. The "superstar cities" attract a growing share of high-paid jobs; medium-sized cities and rural areas have not gained at the same rate. With more people wanting to live in fewer places, prices in those places have risen sharply. The technology and finance sectors particularly drive this clustering.
Housing became an investment asset. The combination of rising prices, favorable tax treatment, and sustained inflation since 2020 has made housing more attractive as an investment rather than just as a place to live. Foreign capital, professional landlords, short-term rental platforms, and large-scale single-family-rental investors all add demand pressure on top of the demand from people who actually want to live somewhere. The consequences are debated; the pattern is real.
Housing as wealth-concentration vehicle
For most non-wealthy households in developed countries, home equity is the single largest piece of wealth. For the middle 60% of US households by wealth, the home made up 64% of assets in 2019; home equity, net of mortgages, was just over a third of their assets (Edward Wolff). In Great Britain, property is the largest part of household wealth, ahead of pensions (2020-22). Home ownership has been the most successful wealth-building tool ordinary people have access to.
That same fact is what makes the affordability crisis politically difficult. Older homeowners have built substantial wealth through the price rises of the last 30 years. Their political and economic interests run against any policy that would substantially lower house prices. Younger renters have the opposite interest but tend to vote less and have less political power. The conflict between these two groups is one of the central political tensions in nearly every country with the affordability problem, even when it is rarely framed in those terms.
The wealth-concentration angle compounds across generations. Children of homeowners inherit, get help with down payments, and grow up in stable housing situations. Children of renters often grow up moving repeatedly, do not inherit, and start adult life without family help with housing. The compounding makes housing a major channel through which wealth and class persistence operate, in ways that affect outcomes far beyond just where someone lives. The Wealth and Inequality page covers this in more depth.
How major cities and countries compare
The affordability picture varies sharply across countries and cities. The numbers below are rough estimates of price-to-income ratios in 2024-2025; they shift year to year.
The takeaway: housing affordability is not a function of any single variable. It is the result of interactions between zoning, geography, immigration, capital flows, tax policy, and political choices about who the housing market serves. The places that have stayed relatively affordable - Tokyo, parts of the US Sunbelt, Vienna - have done so partly through deliberate choices that other places could in principle copy. The fact that they have not is itself a political fact worth examining.
The paths from here
Dated September 2026, with US mortgage rates back above 7%, prices slipping in Sydney, London and Canada, and China's property slump deepening. Housing affordability is one of those problems that grinds on slowly until it reaches a breaking point. The choices below describe the realistic paths.
Continued slow worsening
Land-use rules stay restrictive. Population growth in attractive cities continues. Interest rates stabilize but housing prices stay high relative to income. Family formation continues to be delayed. The political pressure builds without producing decisive reform. The crisis becomes the new normal rather than getting solved.
Will it happen? This is the base case absent serious reform. The pressures have barely eased: just 32% of US households could afford the median-priced home at the end of 2025, and August 2026 housing starts were 1.2% below a year earlier. Most political conversations about housing produce incremental changes that do not move the actual numbers much.
YIMBY-style reform succeeds in specific places
Some cities and states liberalize zoning meaningfully, as the YIMBY ("yes in my backyard") movement urges. Single-family-only zoning is replaced with allowance for duplexes, triplexes, and small apartment buildings. Permitting times are shortened. Environmental review requirements are streamlined for housing projects. Supply rises and prices stabilize or fall in those specific markets while rising elsewhere.
Will it happen? Already happening in some places. California, Oregon, Washington, parts of New England, parts of New Zealand, and parts of Australia have passed reforms in this direction, joined in 2025 by Maine statewide and by Cambridge, Massachusetts. The effects are real but modest so far. Whether the pattern spreads to the most-affected markets is the open question. The coalition is hard to build because those who gain from lower prices (renters, young people) take part in local politics less than existing owners do.
A housing crash provides a partial reset
A combination of higher interest rates, economic recession, demographic shift, and forced selling produces a sustained drop in housing prices in the most-stressed markets. Affordability improves as prices fall to incomes. Existing homeowners take losses; new buyers benefit. The political conflict between owners and renters becomes acute.
Will it happen? Possible in some markets, less likely as a global story. Past major housing crashes (US in 2008, Spain in 2011, Ireland in 2010) involved overbuilding, easy credit, and recession. China shows what a slump after overbuilding looks like: property investment fell 17.2% in 2025 and another 19.9% in January-August 2026, and in August existing-home prices were down on a year earlier in all 70 cities tracked. Most Western markets have built too little rather than too much, which makes a 2008-style crash less likely there. Localized corrections are more probable than the kind of global reset the Great Financial Crisis produced.
A major government building program
One or more rich countries undertakes a Vienna-scale or postwar-Britain-scale public housing program. Direct government building of new housing on government-owned land at non-market prices, with allocation by need, supplements market-rate construction. Prices stabilize in the affected markets and the political coalition behind the program strengthens.
Will it happen? Politically difficult in most rich countries. The fiscal cost is real, the cultural memory of mid-century public housing failures (the British system after the 1970s, US housing projects) is unfavorable, and the local opposition to large new public housing developments is intense. Vienna remains the most successful current example; Singapore has its own version through its Housing and Development Board. Replicating either at scale elsewhere has not yet been attempted; Canada's new federal builder, Build Canada Homes (C$13 billion, 2025), is a first step.
Tax and subsidy reform changes the picture
Mortgage interest deductions are capped or eliminated. Property tax breaks for owner-occupied housing are reduced. Capital gains exclusions on primary residences are tightened. Speculative real-estate investment is taxed more heavily. The advantages of housing as an investment vehicle are reduced; demand pressure eases.
Will it happen? Slowly and unevenly. The political constituency for mortgage and property tax breaks is broad - most homeowners benefit and most homeowners vote. Reform tends to come at the margins (the 2017 US tax law lowered the mortgage interest deduction cap; some Canadian provinces have introduced foreign-buyer taxes). Comprehensive reform has not been politically possible in most rich countries.
The base case is continued slow worsening, with localized reforms that nibble at the edges. YIMBY-style supply reform is gaining ground in specific places; the other paths are real but less central. Housing remains one of the central political and economic issues of the period, with no clean solution in sight.
Where serious analysts disagree
Housing is one of those topics where careful researchers using similar data reach different conclusions about what to do. Each reading below is held by named scholars worth engaging directly.
Supply is the central problem and zoning reform is the central answer
The housing-affordability crisis is, at its core, a supply problem. In the most-stressed markets, restrictive zoning, lengthy environmental review, neighborhood opposition, and political fragmentation between many small jurisdictions have made it nearly impossible to build housing at the scale demand requires. Liberalizing zoning, streamlining permitting, and overcoming local opposition is the highest-leverage policy intervention available. Other reforms (rent control, subsidy programs, tax changes) help at the margins; supply reform goes to the root.
Held by: Edward Glaeser (Harvard), Jenny Schuetz (Arnold Ventures, formerly Brookings), and most of the housing economics profession across the political spectrum. They point to the link between zoning restrictiveness and prices, and to rents: down 7% in fast-building Austin in the year to early 2026, up 9% in supply-constrained San Francisco. The political case for action faces real opposition from existing homeowners.
Investor and speculative demand is more central than supply
The supply story is partly a distraction from the more direct cause: housing has become an investment asset rather than just a consumption good. Foreign capital, professional landlords, large-scale single-family-rental investors, and short-term rental platforms have added demand pressure that supply reform alone cannot offset. Direct interventions on speculative demand (foreign-buyer taxes, restrictions on bulk single-family-rental purchases, vacancy taxes) are needed alongside any supply-side reforms.
Held by: parts of the progressive housing-policy community, some Canadian and Australian researchers responding to specific local conditions. The view shaped the 21st Century ROAD to Housing Act, law since July 2026, which bars investors owning 350 or more single-family homes from buying more from January 2027, build-to-rent aside. Large investors owned about 2% of US single-family rentals in 2022, a quarter in metro Atlanta (Government Accountability Office). Louie, Mondragon and Wieland (2025) add a demand-side challenge: in 2000-2020, income growth predicted the same US house-price growth whatever a city's supply constraints. The data on the magnitude of investor demand effects is contested; the data on its existence is real. Most careful housing economists treat this as a real factor that adds to but does not replace the supply story.
Rent control creates more problems than it solves
The empirical record on strict rent control across multiple countries is consistent: short-term benefits to existing tenants, longer-term reductions in housing supply, deterioration of quality, increased difficulty for new entrants to find housing, and unequal outcomes that benefit better-connected residents over the most vulnerable. The 2019 Diamond, McQuade, and Qian study on San Francisco confirmed and refined this picture. Most professional economists across the political spectrum reach this conclusion despite the political popularity of rent control.
Held by: Rebecca Diamond (Stanford), Tim McQuade (Berkeley), Franklin Qian (now University of North Carolina), Edward Glaeser, and most working housing economists. The Berlin rent-cap experiment of 2020-2021 (struck down by courts but illustrative) reinforced their case. Supporters reply that tenants gain stability and that newer caps, like Washington state's (2025), exempt new buildings; in June 2026 New York City's rent board froze rents on about 1 million stabilized apartments.
The home-as-investment model is the original distortion
Treating housing as both a place to live and an investment asset that should appreciate over time creates an inherent contradiction. If housing prices rise faster than incomes, the next generation cannot afford it. If housing prices fall, current homeowners are politically devastated. The system as designed produces the affordability crisis as a feature, not a bug. Resolving it requires reframing housing as primarily consumption, with policy that does not subsidize owner-occupiers as investors.
Held by: the Henry George tradition, economists such as Josh Ryan-Collins (University College London), who blames a feedback loop between mortgage credit and land prices, and housing-rights advocates. The argument is theoretically clean and politically very difficult; making homeowners worse off as a class has not been a politically successful program in any rich country.
Successful examples exist and could be copied
Tokyo demonstrates that a major global city can stay affordable through permissive national zoning. Vienna demonstrates that a major Western city can stay affordable through large-scale public housing. Singapore demonstrates that an entire small country can manage housing through the Housing and Development Board model. Each is replicable in principle; the political will to do so has been the binding constraint, not the technical feasibility.
Held by: urbanists such as Alain Bertaud (NYU), a critic of rigid land-use rules, admirers of the Vienna and Singapore models, and a small body of comparative urban economics. The argument is that the housing crisis is more solvable than is usually presented; what is missing is the political coalition to actually solve it. Skeptics point to record new-flat prices in central Tokyo.
What the available evidence actually supports: supply is a central long-run problem in the most expensive markets, though new work suggests demand matters more than once thought. Investor demand and speculative dynamics add to it in some markets; strict rent control mostly fails; the home-as-investment model creates built-in contradictions; and successful examples exist but require political will most countries have not yet generated. The practical implication is that a comprehensive housing reform requires liberalizing supply, addressing speculative demand, avoiding rent-control mistakes, and building the political coalition for major change. Few countries are doing all of these simultaneously.
What this means for you
Housing touches every reader's life directly. A few practical observations:
If you are renting and want to buy
The math is harder than it was for previous generations. Down-payment requirements have grown faster than wages. The hardest decision is often whether to compromise on location to enter the market at all (which often makes financial sense) versus waiting for the market to become more accessible in your preferred area (which historically has not happened on the timescale most people want). The single highest-leverage variable for whether you can afford a home in a stressed market is whether your family has wealth to help with a down payment - not a comfortable observation, but a true one.
If you own a home
Your home is probably your largest single asset. The price rise of the last 20 years has been a windfall to your generation. The political conversations about housing affordability in your country are partly a conversation about whether to reduce that windfall for the benefit of younger and less wealthy households. Whether you support reforms that may slow your home's appreciation in exchange for broader access, or oppose them, is a civic choice worth making deliberately.
If you are choosing where to live
The cost of housing has become one of the most important variables in life-planning decisions. A more affordable region with a moderately worse job typically delivers a better life than an expensive region with a moderately better job, because the housing-cost premium absorbs most of the pay difference. Mid-sized cities with strong economies (Austin, Nashville, Raleigh, Lyon, Manchester) have become a sweet spot for many. The trade-offs are real and worth thinking about explicitly rather than defaulting to the most prestigious city option.
If you are voting on local issues
Most housing policy is local: zoning decisions, building permits, transit investment, tax assessments. The local councils, planning commissions, and ballot measures that affect housing are typically decided by small numbers of engaged voters - and the engaged voters tend to be older homeowners. Younger and renter voters who actually show up to local hearings and elections have outsized influence. Voting on the merits of specific zoning reform, transit investment, and housing-policy proposals is one of the highest-leverage civic activities available.
If you are thinking about your children's future
The housing-affordability gap is one of the largest single drivers of generational inequality. Help with a down payment is one of the highest-leverage transfers parents can make to adult children, far more impactful than smaller cash gifts spread over years. If you are in a position to help, doing so deliberately and early often produces better outcomes than waiting until inheritance. If you are not in that position, encouraging your children to consider less expensive regions early in their careers is one of the most useful pieces of life advice available.
The mechanics behind this
The housing story sits on top of three deeper mechanisms covered elsewhere on this site. If the analysis above depends on ideas you want to understand first, these fundamentals make the conversation more legible:
