Why Is Housing So Expensive?

Why the Supply and Demand Explanation Falls Short

Why is housing so expensive? When you ask this question, politicians and economists reach for the same answer: supply and demand. Not enough homes have been built. Zoning laws are too restrictive. NIMBYs block development. If only we built more, prices would fall. The solution, in this framing, is technical — update the planning rules, incentivize developers, release more land for construction.

This framing has one remarkable feature: it treats the current arrangement of land ownership as a natural baseline, and asks only how to make it function more efficiently. It never asks the prior question — why is land privately owned at all? Why does a piece of the earth's surface, which no one made and which preceded every human institution by billions of years, belong to specific individuals who can charge others for the right to exist on it?

That question sounds radical. But it was once perfectly mainstream. The history of how land became a commodity — how something that was common became private — is the history of some of the most deliberate, violent, and politically contested decisions in human history. Understanding it doesn't just explain why housing is so expensive. It explains how money and markets came to feel like nature — because the same logic that made land ownership seem inevitable is what made markets seem inevitable.

How Did Land Become a Commodity?

For most of human history, the idea that someone could permanently own a piece of land — could exclude others from it, sell it, pass it to heirs, sit on it idle while charging others rent — would have been incomprehensible. Land was something communities used. It was managed collectively, governed by custom, and understood as belonging to no one in the same way air and water belonged to no one.

In medieval England, the system that prevailed for centuries was the commons. Open fields, meadows, forests, and fens were available to the people of a village for grazing, gathering firewood, cutting peat, and gleaning after harvest. No single person owned these resources. The right to use them was attached to your membership in the community, not to any deed or title. You had rights in the land. You did not own it.

This was not a state of primitive chaos. It was a stable, sophisticated system that had sustained rural communities for generations. The question of what replaced it — and why — is where the real history begins.

The Enclosures: Land Theft by Parliamentary Act

Between roughly 1500 and 1850, the English commons were systematically abolished. Through over 5,000 Enclosure Acts, Parliament transferred millions of acres of common land into private ownership. Hedges were built. Fences went up. People who had grazed their animals on common land for generations were told that the land now belonged to a landlord, and they were trespassing.

The beneficiaries were almost exclusively the landowning aristocracy and the emerging capitalist class. The people who lost were the peasants, the cottagers, the rural poor — everyone who had depended on common land for subsistence. Almost overnight, they had nothing to sell but their labor. Which was, of course, the point.

Enclosure was not just an economic policy. It was a project of social discipline. Common land gave people an exit option. If you could grow food, gather wood, and graze animals on the commons, you were not entirely dependent on wages. Enclosure destroyed that independence. It created a class of people who had no choice but to work for whoever owned the means of production — because the alternative was starvation. The wage labor system that we now treat as natural was constructed, violently, through the expropriation of the commons. (Federici, Caliban and the Witch, 2004)

Contemporary observers were clear about what was happening. Thomas More, writing in Utopia (1516), described sheep eating men — the wealthy converting arable land to pasture for wool production, driving peasants off their holdings and into beggary. This was not invisible. It was obvious, condemned, and done anyway, because it served the interests of the powerful.

Land as a Fictitious Commodity

Land, labor, and money are not ordinary commodities. None of them were manufactured for sale — land is not made, labor is human life, money is a social institution. Yet the market system treats them as if they were, subjecting them to price, supply, and demand like any other product. (Polanyi, The Great Transformation, 1944)

These things are not produced for sale. Land is not manufactured. Labor is human life — it cannot be separated from the person performing it. Money is a social institution, not a natural resource. Treating these as ordinary market commodities, Polanyi argued, was not a discovery of some natural economic order. It was a political project, violently enforced, that subordinated society to the market rather than the other way around.

Before the market economy, land was embedded in social relations. You had obligations to those who worked it. You had obligations to the community that surrounded it. The idea of treating land as purely a financial instrument — buying it low, selling it high, extracting maximum rent, leaving it idle if that produced better returns — required dismantling centuries of social obligation and replacing them with the single logic of price.

Enclosure was a revolution of the rich against the poor. That description fit England in the 18th century. It fits London, Sydney, Toronto, and San Francisco today.

How Housing Became a Financial Asset

The enclosures created private land ownership. But they did not, by themselves, create the current housing crisis. That required a further step: the transformation of land and housing from a place to live into a vehicle for financial speculation.

Mortgage Deregulation and the Finance Flood

Until the 1970s and 1980s, housing in most wealthy countries operated under significant constraints. Mortgage credit was regulated. Interest rates were controlled. Speculation was limited. Then came financial deregulation. In the UK, the 1986 Big Bang deregulated financial markets. In the US, the Depository Institutions Deregulation and Monetary Control Act (1980) and the Garn-St. Germain Act (1982) loosened controls on mortgage lending. Pension funds, insurance companies, and eventually global investment capital were permitted — and encouraged — to flow into property markets.

The effect was immediate and predictable. When you flood a market with cheap credit, prices rise. More money chasing the same supply of land drives up prices. Landlords found they could charge more. Speculators found they could buy property, hold it, and sell it at a profit — even without doing anything useful with it. Housing began to function less like shelter and more like stock: something you held as an investment, something whose value came not from use but from the expectation that someone else would pay more for it in the future.

This was not a slow drift. It was a series of decisions. Property prices rose. People who owned property before the deregulation became wealthier. People who didn't, paid for it — in rent, and in the higher prices they eventually had to borrow to meet.

The Tax Subsidies That Made It Worse

The financialization of housing was not just permitted by policy. It was actively subsidized. In the United States, the mortgage interest deduction allowed homeowners to deduct mortgage interest from taxable income — worth tens of billions of dollars a year, flowing predominantly to wealthy homeowners with large mortgages. Capital gains on property sales were taxed at lower rates than wages.

At the same time, taxes on land value were abolished or allowed to atrophy. Land value tax — which falls on the unimproved value of the land itself, not the buildings on it — is one of the most economically efficient taxes ever theorized. It cannot be passed on to tenants. It cannot be avoided by relocating or restructuring. It penalizes land banking and idle speculation. Virtually every serious economist across the political spectrum has endorsed it at some point.

It has not been implemented anywhere at meaningful scale, because the people who own land also tend to own the political process.

Henry George and the Road Not Taken

In 1879, Henry George published Progress and Poverty. The argument at its centre was both simple and devastating.

George noticed a paradox: as societies became richer through industrial progress, poverty was not declining. Where was the wealth going? To the landowners. The gains from economic progress — better infrastructure, denser cities, rising productivity — automatically accrued to those who owned land in the right places. A railway line is built through a city. Everyone who owns land near the stations becomes richer, simply by owning. They did nothing. They produced nothing. But the value of their land increased because of collective investment in public infrastructure. This value — which George called “economic rent” — was extracted by private landowners who had done nothing to create it.

His solution: tax away all economic rent through a single land value tax. Leave the returns to labor and capital, but capture for the public the value that society collectively creates through its presence and investment. Abolish all other taxes. Fund public goods directly from the wealth that belongs to the commons.

George's ideas terrified the landowning classes precisely because they were so hard to argue against on purely economic grounds. The pushback came not from rational refutation but from political suppression. His movement was deliberately marginalized in economic education over the following decades. Standard economics textbooks folded “land” into “capital,” erasing the distinction that made George's analysis so dangerous. If land is just another form of capital, there is nothing special about landownership — no need to treat it differently, tax it differently, or question it at all.

Who Benefits from High House Prices

The housing crisis is presented as a problem everyone shares. This is false. Whether high house prices hurt you or help you depends entirely on your relationship to property ownership.

For renters — disproportionately young, working-class, and from racial minorities — high house prices are catastrophic. They mean spending 30%, 40%, sometimes 50% of income on housing. No asset accumulation. No inheritance to pass on. Permanent vulnerability to a landlord who can raise rent, sell up, or evict.

For mortgaged homeowners, high house prices are a mixed blessing. They feel wealthy on paper. Their home is their pension plan. They vote against new construction and against any policy that might bring prices down. Their retirement savings are in that house — that's not a mistake they made, it's the trap that was set for them. Pension funds were hollowed out over decades. Savings accounts pay nothing. The only wealth-building mechanism left for most people is a house that goes up in value. So they walk into the trap and then vote to keep it in place, because the alternative is losing the one thing standing between them and poverty in old age.

For large-scale property investors — developers, REITs, private equity firms, offshore wealth funds — high house prices are straightforwardly profitable. Blackstone alone owns more than 300,000 rental homes in the United States. They hold assets that appreciate. They extract rent. They use housing scarcity as a business model.

The political system consistently chooses policies that inflate prices and benefit owners over renters, speculators over people who need somewhere to live. This is not an oversight. It is the outcome of a political system that is more responsive to property owners than to those without property.

Why Does Owning Property Build Wealth but Renting Doesn't?

Why does owning property build wealth but renting doesn't? The usual answer is about equity: when you own, your mortgage payments build ownership in an asset. But this misses the deeper structural explanation.

In a financialized housing market, homeowners simultaneously pay for shelter and capture rising land values — the economic rent that George described. This rising value is not created by anything the homeowner does. It comes from the collective activity of the city: new infrastructure, economic density, public investment, the simple presence of millions of people making the location desirable. The homeowner captures this value. The renter pays it, in the form of rent increases that track rising land prices.

This means wealth accumulation through homeownership is not a reward for thrift or hard work. It is a structural transfer of value from renters to owners — a mechanism that enriches those who already have assets at the expense of those who don't. It operates completely independently of individual choices or merit.

The policy implication should be obvious: if you want to reduce wealth inequality, you need to change the system that makes housing an investment vehicle. But changing that system means reducing house prices — which means hurting the asset values of the homeowning class, who are the most politically engaged, the most likely to vote, the most likely to donate to political parties.

Colonial Enclosure: The Same Story Globally

The enclosure of common land was not a uniquely English event. It was a template that European colonizers exported across the globe, with consequences that remain unresolved.

In Africa, Asia, and the Americas, colonizers encountered land-use systems that looked like the English commons — communal, governed by custom, not alienable as private property. They proceeded to enclose them. The legal instruments varied: homestead acts, crown land declarations, native reserve systems, registration requirements that extinguished customary rights. The logic was identical: define common land as “unoccupied” or “waste,” vest it in colonial state or private ownership, and force the people who depended on it into the wage economy.

The hut tax — imposed across British Africa in the late 19th and early 20th centuries — was a precise mechanism for this: tax people in cash for the right to live in their own homes, then force them to seek wage labor when they couldn't pay. Land enclosure and labor coercion were not separate policies. They were two sides of the same coin.

What the Supply Argument Gets Wrong

The standard response to housing costs is: build more. The supply is constrained, prices are high, so add supply. This sounds like common sense. It is also, on its own, a way of avoiding the actual question — because it accepts private land ownership as the unchallengeable starting point and asks only how to add more product within that system. Three things the supply argument cannot explain:

First, in a financialized housing market, new supply does not automatically become affordable housing. Developers build for the most profitable segment of the market. In cities with extreme land costs, that means luxury development. New luxury supply may eventually filter down over decades, but the timeline is cold comfort for people who need housing now.

Second, the supply argument sidesteps the question of ownership. Even if you build enough homes to house everyone, if those homes are owned by private investors and rented at market rates, you have not solved the problem of housing insecurity — you have merely displaced it. The wealth transfer from renters to owners continues.

Third, the supply framing accepts land privatization as unchallengeable. It asks how to produce more housing within a financialized system, not why housing is financialized in the first place. It is a technical question posed in place of a political one.

What the Record Shows — and Why It Was Taken Away

Vienna Built It. Thatcher Sold It.

Vienna has maintained municipal housing — Gemeindebau — since the 1920s. Roughly 60% of Vienna's population lives in publicly subsidized housing. Rents are capped. Tenure is secure. Vienna consistently ranks among the world's most livable cities, with housing costs that are a fraction of London's or San Francisco's. It works. It has worked for a hundred years.

Britain had something like this. By 1979, council housing provided homes for roughly 30% of the population — not a marginal program, a mainstream housing option. The Thatcher government introduced Right to Buy in 1980: tenants could purchase their council homes at below-market prices. Over 1.5 million homes were sold off. Councils were then barred from using the proceeds to build replacements. A two-step transfer: sell the public asset at a discount, then prevent its replacement. The people who bought got an asset. Everyone who came after got a longer waiting list and a private landlord.

This is not a story about where housing policy went wrong. It is a story about who benefits from housing being scarce and expensive — and who controls what gets passed into law. The people who took the council housing are the same people who now collect rent on it.

The Solution No One Will Pass

A tax on the value of land — not the buildings on it, just the land itself — would collapse the investment logic of property ownership. You cannot pass it on to tenants. You cannot avoid it by restructuring. It makes sitting on empty land expensive and building on your land relatively cheaper. Economists have endorsed this for 150 years, since Henry George made the case in Progress and Poverty in 1879.

It has never been implemented at meaningful scale. Not because it doesn't work. Because the people who own land also, largely, control who gets elected. The barrier is not intellectual. It is the same barrier that prevented the commons from being restored after enclosure: the people who benefit from the taking are in charge of deciding whether to give it back.
