Why Housing is Expensive

Housing has quietly become one of the defining crises of our age. Across nearly every advanced economy the pattern is the same: rents devour paychecks, mortgages stretch across a lifetime, young adults postpone independence and family, and even essential workers are pushed far from the communities they serve. What once anchored middle-class life now slips out of reach. This is not a passing cycle; it is a structural break that reshapes economies, social mobility, and demographic futures.

The book begins with a simple question-how did we get here? For much of the twentieth century, a modest home cost two to four years of income; ownership was plausible on a single salary, and communities prospered on that stability. Today, price-to-income ratios of six, ten, even fifteen to one have become common across global cities, while rent burdens make saving nearly impossible. We trace the forces behind this shift. Financialization recast homes as tradable assets, tying local prices to global capital rather than local wages. Manufactured scarcity-zoning rules, permitting mazes, political vetoes-chokes supply where it is needed most and converts land into a speculative bottleneck. A powerful political lock-in then defends the status quo, as mortgage-dependent systems and incumbent homeowner interests resist any change that might lower prices.

We show how this system harms far beyond housing. When shelter drains income, consumption falters and investment tilts toward unproductive real estate instead of innovation. Labor mobility stalls, entrepreneurship withers, inequality widens between owners and renters, and family formation is delayed-one reason fertility has fallen across much of the developed world. These are not isolated stories; they are the macroeconomy made personal.

The book examines what nations have already tried-and why half-measures fail. Celebrated models and ambitious programs across the world offer lessons and limits alike: sustained public building can work, but subsidies in supply-constrained markets backfire; large stocks of housing help, but speculation can still overwhelm access.

Summarizing this global evidence, the closing chapters present a clear proposal to resolve the housing question: treat housing as essential infrastructure and deliver it through an industrial-scale system designed for speed, quality, and cost control, paired with clean, public financing that anchors prices to wages-a Public Mortgage Bank and complementary institutions that keep homes affordable and stable over time. Scarcity is not natural; it is manufactured. Because it is manufactured, it can be dismantled.

This book is a condensed, journalistically rewritten and improved version of the author’s more technical volume Why Housing Became Unaffordable: And How to Fix It.
