Why Affordability Is Being Questioned NowHave you ever come across the word "affordability"? At its most literal, it refers to whether something is within one's financial reach, but the concept carries far greater weight than that. It describes whether the fundamental costs of living — housing, healthcare, education, food — fall within a manageable range relative to a person's or household's income. In other words, it asks a deceptively simple question: can people live a normal life?There was a time when affordability was a term confined to economists and policy specialists. Today, it appears in political speeches, news headlines, and street interviews alike. The reason is straightforward: the once-taken-for-granted assumptions that "work and you can get by," "save and you can own a home," and "your children can access education" are rapidly disappearing in country after country.Since the 2020s in particular, the economic disruption caused by the COVID-19 pandemic, the subsequent acceleration of inflation, and a dramatic surge in housing prices have combined to push affordability to the forefront of social debate, in both developed and developing nations. In Japan, wages have failed to keep pace with rising prices, and among younger generations especially, a deep anxiety about the future has taken root. This essay traces how the concept of affordability was born, how it has evolved, and what kind of crisis it now presents to modern societies.The Origins and Original Definition of AffordabilityThe concept of affordability began to be used seriously in economic policy circles from the mid-20th century onward. In postwar Europe and North America, rapid urbanization and population growth brought housing access to the forefront as a social problem. To express the goal of "supplying housing that even lower-income households could access," the term affordable housing came into widespread use.The definition at the time was refreshingly simple. The most widely adopted benchmark was what became known as the "30 percent rule": a household spending no more than 30 percent of its income on housing was considered to be in an affordable situation. This standard was adopted as a federal guideline in the United States during the 1980s and went on to influence housing policy in Japan and many other nations.The same thinking spread beyond housing. In healthcare, affordability came to mean a state in which receiving necessary medical treatment does not cause financial ruin. In education, it meant being able to study without excessive reliance on scholarships or debt. In food, it described a situation in which nutritious meals could be secured every day. The common thread across all these domains was the same fundamental question: can people obtain what they need to maintain a basic standard of living without sacrificing an unreasonable proportion of their income?Crucially, affordability does not simply mean cheapness. If prices are low but income is even lower, something is not affordable. Conversely, if prices are high but income comfortably covers them, something can still be affordable. The concept is always about the relative balance between income and expenditure. This elegant and essential definition would, in time, come under enormous strain.The Gap Between Definition and Reality: What Has Changed?So what exactly has opened up between the original definition and the lived reality of today? Housing affordability offers perhaps the clearest illustration.In the era when the 30 percent rule was established, it was entirely realistic for middle-income Americans to take out a mortgage and purchase a house in the suburbs. Economic growth and wage growth moved in tandem, and housing prices broadly reflected those movements. From the 1990s onward, however, and most acutely from the 2000s through the 2020s, housing prices in major cities surged at a pace far outstripping wage growth.In the United States alone, the national median home price rose by more than 40 percent between 2020 and 2023, while wages grew by only around 15 to 20 percent over the same period. As a result, middle-income households in many cities now find themselves spending upward of 50 percent of their income on housing. The 30 percent rule has become a relic increasingly divorced from reality.In Toronto and Sydney, average home prices have reached 10 to 15 times the average household income, making it structurally impossible to "work an ordinary job and buy an ordinary home." London and New York tell a similar story: homeownership has effectively become the preserve of the wealthy or those who have inherited assets from their parents.Japan is not immune. The average price of a new condominium in the central wards of Tokyo exceeded 100 million yen for the first time in 2023. Even outside the capital, a combination of urban population concentration and rising construction costs has pushed housing prices steadily higher, at the same time that Japan's real wages have stagnated for roughly 30 years.The problem extends well beyond housing. Medical costs present serious challenges in their own right. In the United States, even insured patients frequently face high out-of-pocket expenses, leaving families perpetually vulnerable to financial collapse triggered by illness. In Japan, the universal health insurance system provides a buffer, but the growing burden of medical and long-term care costs tied to an aging population is squeezing household finances. In anglophone countries where university tuition has skyrocketed, student loan repayments have become a millstone around the necks of younger generations, delaying homeownership, marriage, and starting families.Food affordability has deteriorated sharply since the inflationary wave that began in 2022. Rising food prices hit lower-income households hardest, because food represents a proportionally larger share of spending as income decreases. In the United Kingdom, food bank usage has surged in recent years, and the phenomenon of "working poor" people who are employed but cannot afford adequate nutrition has become an entrenched feature of advanced economies.What all these changes demonstrate is that the foundational assumption underlying the original definition — that economic growth, wages, and prices would move in rough alignment — no longer holds. In a globalized and financialized world, asset prices have soared while wages have stagnated and living costs have climbed. The affordability crisis is not a problem that individuals can solve through effort or frugality. It is a crisis embedded in the very structure of the economy and society.The Wider Social Cost: The Damage That Is Hard to SeeThe affordability crisis is far more than a matter of household budgets. It is reshaping how people live and altering the very fabric of society.The most visible consequence is the decline in birth rates and the broader demographic transformation it triggers. When housing and education costs remain prohibitively high and income uncertainty looms large, younger generations delay or abandon marriage and parenthood. Japan's falling birth rate has multiple causes, but surveys consistently show that a sense of lacking the financial room to raise children is a central factor. In South Korea, the pattern is even more extreme: the total fertility rate has fallen to the 0.7 range, and the crushing weight of housing and education costs is widely cited as a primary driver.Geographic inequality and population displacement present another dimension of the problem. As living costs in urban centers rise, younger and lower-to-middle income residents find it increasingly impossible to stay, and are pushed into long commutes or forced to relocate to suburbs and rural areas. This hollows out and homogenizes urban communities, eroding their diversity. Meanwhile, the areas receiving these displaced populations can experience their own wave of price increases, pushing out original residents in a process commonly called gentrification.The mental and physical health consequences are equally serious. Living with housing costs that consume the bulk of one's income, perpetually anxious about rent payments or mortgage obligations, generates chronic stress. A substantial body of research links financial insecurity to higher rates of sleep disorders, depression, and anxiety. The freedom from financial worry is not a luxury; it is a foundation of health.Perhaps most consequentially for the long term, affordability pressures are corroding the pillars of democratic society. When people feel that their lives are not sustainable, distrust in existing political and economic institutions deepens. The rise of populism and the intensification of social division across Europe and North America cannot be understood without reference to the affordability crisis lurking beneath. When trust in the social contract — the belief that effort will be rewarded — breaks down, people seek outlets for their anger and despair. The result manifests as backlash against established politics and growing support for parties and leaders with extreme agendas.Taken together, these consequences reveal that the affordability crisis is not merely an economic problem but a challenge to the social cohesion and democratic foundations of modern societies. That is why superficial remedies — price controls here, cash handouts there — are insufficient. Structural solutions are what the situation demands.Looking Ahead: How to Redefine and Restore AffordabilityWhat, then, should society do in the face of this crisis? And how might the concept of affordability itself need to evolve going forward?The first necessity is updating the definition. Simple ratios like the 30 percent rule are no longer adequate to capture the complexity of modern living costs. What is needed is a more comprehensive measure that aggregates housing, healthcare, education, food, transportation, and communications expenses, and asks whether the total is sustainable relative to income.International organizations and researchers are already moving in this direction. The OECD and the IMF are both developing frameworks that approach affordability from a whole-of-life perspective rather than limiting the lens to housing alone. In Japan, the concept of "real purchasing power" — measuring the balance between prices and wages — has drawn growing attention from policymakers and commentators.On the policy front, governments around the world are experimenting with a range of approaches. In housing, debates center on expanding public housing stock, relaxing regulations that limit land use, and imposing taxes on speculative property purchases. Canada and several European countries have moved to restrict property purchases by foreign nationals and corporations, with the results still being evaluated. In healthcare and education, the Nordic model of generous public provision as a guarantee of individual affordability is attracting renewed interest.Wage policy is equally important. Raising the minimum wage is the most direct instrument available, but it is not sufficient on its own. More fundamental reforms are needed: mechanisms that tie wage growth to productivity gains, and improvements in the treatment of non-regular workers. Japan's government has been raising the minimum wage in recent years, but many argue that the pace needs to accelerate further to keep up with rising prices.Technology and innovation offer additional pathways. Advances in construction methods could reduce housing costs. Digital health platforms could make healthcare more efficient and accessible. Online education could bring down the cost of learning. Yet these technological solutions carry the risk of widening disparities between those who can benefit from them and those who cannot, which means that equity must be designed into their deployment from the outset.In the long run, the affordability problem connects to the most fundamental question in political economy: how should the fruits of economic growth be distributed? So long as growth enriches asset holders disproportionately while failing to raise living standards for workers, no amount of aggregate economic expansion will improve the affordability of daily life for most people. Tax reform, narrowing the wealth gap, and strengthening social safety nets represent the core of a durable solution.Finally, perhaps the most important shift needed is a change in how we frame the problem itself. Affordability is not a matter of individual choices or personal discipline. It is a question of how society is designed. Rhetoric that places responsibility entirely on individuals — "just save more," "just earn more" — obscures the structural inequalities at the heart of the crisis. The time has come for a society-wide reckoning with what we prioritize, what we invest in, and what we are willing to change, in order to restore the basic foundation that ordinary work should make for an ordinary life.Affordability is not merely an economic indicator. It is the question of whether life in this society is possible. Ensuring that the answer remains yes demands nothing less than a renewal of definitions, a transformation of policy, and a fundamental shift in how we understand our obligations to one another.References・ Harvard Joint Center for Housing Studies, "The State of the Nation's Housing 2023" ・ OECD, "Affordable Housing Database", 2023 edition ・ IMF, "World Economic Outlook: Navigating Global Divergences", October 2023 ・ The Economist, "The housing theory of everything", September 16, 2021 ・ Ministry of Land, Infrastructure, Transport and Tourism (Japan), "FY2023 Housing Economy Data" ・ Statistics Bureau of Japan, "Consumer Price Index Annual Report", 2023 edition ・ Ministry of Health, Labour and Welfare (Japan), "Basic Survey on Wage Structure", 2023 edition ・ Cabinet Office of Japan, "Annual Report on the Japanese Economy and Public Finance 2023" ・ Matthew Desmond, "Poverty, by America", Crown Publishing Group, 2023 ・ Masaru Kaneko and Noriko Hama, "The Great Failure of Abenomics and Japan's Economic Predicament" (Kamogawa Shuppan, 2018) ・ Yukio Noguchi, "The Essence of Yen Depreciation and Price Increases" (Diamond Inc., 2023) ・ Richard Reeves, "Dream Hoarders", Brookings Institution Press, 2017 ・ Anne Power, "Estates on the Edge: The Social Consequences of Mass Housing in Europe", Macmillan, 1997 ・ Statistics Canada, "Housing Statistics in Canada", 2023 edition
