Why is it so hard to create affordable housing in large European and US cities, and how can it be fixed?
Cities must build housing like infrastructure — with public finance and long-term planning — because private markets build only for the highest bidders.
Roosevelt shows that direct government construction works when private capital won't build for lower incomes. Thatcher proves that property ownership creates stability, but only after someone builds the housing stock. Lee demonstrates that state development with forced savings can house entire populations affordably. Keynes explains why housing markets cycle between speculation and shortage, requiring patient public investment.
The split is over method, not necessity: direct provision versus deregulated supply versus state development corporations.
Confidence summary: Strong convergence that private markets alone cannot solve affordable housing, with tactical disagreement on state roles.
1. The core argument
When Franklin Roosevelt created the Public Works Administration housing division in 1933, he grasped what today's cities have forgotten: developers build for profit, which means they build for whoever pays highest prices. This isn't market failure — it's market logic. The council agrees that private capital systematically excludes lower-income families because adequate profit margins require higher rents than these families can afford. Margaret Thatcher's Right to Buy succeeded precisely because Britain already possessed substantial council housing stock to sell. Someone had to build that stock first. Lee Kuan Yew's Housing Development Board housed 87% of Singaporeans by treating residential construction like airport development — essential infrastructure that markets underprovide. John Maynard Keynes identifies the temporal problem: housing markets cycle between speculative bubbles and credit contractions, but demographic need for shelter persists regardless. Only public investment bridges this mismatch reliably.
2. How each member frames it
Franklin D. Roosevelt sees affordable housing as public works infrastructure, requiring direct government construction and finance when private markets exclude entire income groups. Public housing serves economic necessity, not charity.
Margaret Thatcher reframes the question as regulatory failure rather than market failure. Planning restrictions create artificial scarcity. Free land markets and streamline approvals, and supply will follow demand. Property ownership transforms behaviour from dependency to responsibility.
Lee Kuan Yew views housing through infrastructure strategy. The state must build supply, but individuals should own assets through mandatory savings schemes that convert forced thrift into property ownership.
John Maynard Keynes diagnoses speculative cycles that create boom-bust patterns in housing supply. Patient public capital captures social returns that private developers cannot monetise.
3. Where the council agrees
The most surprising consensus emerges around market limitations: all members accept that private developers cannot profitably house lower-income families in expensive cities. Even Thatcher acknowledges this implicitly — her Right to Buy required existing public housing stock to function. Roosevelt's 1937 Housing Act, Lee's Housing Development Board, and Thatcher's council house sales all succeeded because government first created supply. The council converges on housing as infrastructure requiring long-term planning horizons that private markets cannot sustain. They agree that property ownership creates superior outcomes to rental dependency, but recognize that ownership requires either public subsidy or mandatory savings to achieve affordability. Keynes and Roosevelt identify identical patterns: housing markets exhibit speculative cycles disconnected from demographic need, requiring counter-cyclical public investment to maintain adequate supply.
4. What would change this verdict
If land costs fell dramatically through technology or policy, private markets might build affordably without subsidy. If mandatory savings schemes proved politically impossible in Western democracies, direct public provision might become the only viable path.
