Housing as Everything

Here's an incomplete list of things that housing costs affect: wages, productivity, innovation, inequality, fertility, obesity, climate change, political polarization, financial crises, and regional convergence. It's the kind of claim that should make you suspicious — a single cause explaining everything usually means someone is overselling. But the evidence is annoyingly strong.¹

Start with the numbers. New York metro area house prices are up 706% since 1980. San Francisco: 932%. London: over 2,100%. Sydney: 1,450%. In all cases, prices have risen vastly faster than wages. And unlike almost everything else — TVs, fridges, cars — housing has gotten more expensive in real terms, not less. The median American worker in 1975 needed 65 hours to buy a fridge-freezer; by 2013, it was 20 hours. Housing went the other direction.

The obvious explanation is supply. Prices range from about two to four times the actual cost of building equivalent new homes. That wedge is a rough measure of how much cost is being driven by restrictions on building. Tokyo and Seoul, which allow relatively easy construction, don't see the same price dynamics. When demand rises in those cities, supply rises too, instead of just prices.

The Hidden Cascades

The obvious effect of expensive housing — less money for everything else — is only part of the story. The hidden effects come from how people change their behavior when housing is scarce.

Productivity: When a software engineer can't afford San Francisco, she moves to a cheaper city and takes a less productive job. But it's not just her productivity that drops — the people she would have worked with lose the benefits of collaboration too. One study estimated that if just three US cities (New York, San Jose, San Francisco) loosened building rules to the national average, total US GDP would be 8.9% higher. That's roughly the size of the COVID contraction. Other estimates go as high as 25%, or $16,000 per person per year.¹

Innovation: Nearly all innovation happens in cities, and the most valuable innovations happen at density. US evidence from 600,000+ patents shows that unconventional breakthroughs benefit specifically from high-density urban environments. For software, the knowledge spillover dissipates within 10 miles; for advertising, within half a mile. By limiting who can live in places like the Bay Area, we're not just losing productivity — we're losing ideas.

Inequality: This is where things get interesting, because the housing story reframes one of the biggest debates in economics. Thomas Piketty famously demonstrated that the share of national income flowing to capital (rather than labor) has been rising across the developed world — his r > g argument that returns on wealth outpace economic growth, generating a neo-Victorian society of inherited fortunes.² But a closer look at the data reveals something Piketty underemphasized: in the US at least, the rising capital share is almost entirely driven by housing. It's really an increase in the share going to landowners, driven by restrictions on building.¹

This connects to an insight that's over a century old. Henry George argued in Progress and Poverty that improvements in a local area — a new park, better sanitation, a transit line — get captured by landowners, because they make people willing to pay more to live nearby. The gains from collective investment flow to whoever holds the scarce asset. George's proposed solution was a tax on land value, an idea that keeps resurfacing because the underlying logic is so clean.

Fertility: Across the developed world, women have fewer children than they say they want. A 10% rise in house prices is associated with a 1.3% fall in births. Given the housing cost increases of the past four decades, this implies a massive fertility suppression. One estimate: UK housing cost increases between 1996 and 2014 led to 157,000 fewer children.

Obesity: This one's less obvious. Japanese land use regulation allows dense, walkable cities — Tokyo and Osaka, where 12-13% of trips are by private car, compared to 85% in Los Angeles and 91% in Houston. The average Japanese person walks thousands more steps daily. Manhattan has an obesity rate one-quarter the national average. The built environment created by housing policy literally shapes bodies.

Algorithmic Landlords

If the structural problem is supply restriction, the short-term problem is market power. A ProPublica investigation found that a Texas company called RealPage had become the dominant provider of rent-setting software after a controversial 2017 merger. In some Seattle neighborhoods, 70% of apartments were managed by companies using RealPage pricing algorithms.³

The software explicitly discourages leasing agents from showing empathy. One developer said agents had "too much empathy" compared to computer-generated pricing. The system sometimes recommends landlords accept lower occupancy in order to push rents higher — a strategy that benefits all landlords collectively, at tenants' expense. One executive described it as a "rising tide lifts all boats" approach. About 90% of the algorithm's suggestions are adopted.

The RealPage story is a concrete instance of what economists have been warning about in more abstract terms: when competitors share pricing data through a common algorithm, the result looks a lot like a cartel, even without anyone explicitly conspiring. It's the invisible hand replaced by an invisible algorithm — except instead of reaching equilibrium, it ratchets upward.

The Georgist Answer

Norway offers perhaps the clearest real-world test of Georgist thinking applied to a different resource.⁴ When the country discovered massive North Sea oil reserves, an Iraqi-Norwegian petroleum geologist named Farouk Al-Kasim helped design a system that taxed extraction at 78% while massively subsidizing exploration and R&D. The logic: this isn't your oil, it's the people's oil. If you want it, you must compensate the people.

The result was the opposite of the resource curse that plagues most oil-rich nations. Norway's extraction rate averages 45% versus a global average of 25%, because the tax system incentivizes squeezing every drop efficiently. The revenue flows into a sovereign wealth fund — now worth over $1.5 trillion — that invests globally for the benefit of future generations. Companies are encouraged to spend on innovation and discovery (which they can deduct) rather than hoarding extraction rights.

Al-Kasim's system avoided both the Scylla of corporatist privatization (the American model, where companies keep the profits and leave communities to clean up) and the Charybdis of state socialism (the Middle Eastern model, where nationalized monopolies stifle competition). "Competition is the essence of competence," he said. The private companies compete; the state captures the rents.

Applied to housing, the Georgist logic would say: tax the land value, not the building. You didn't create the land. The community's collective investment — roads, schools, parks, jobs — is what makes it valuable. A land value tax would discourage speculation (holding land idle is expensive when you're taxed on its value regardless), encourage development (improvements aren't taxed, so there's no penalty for building), and capture for the community the value that the community created.

It's a clean theory. The reason it hasn't been widely implemented has less to do with economics than with politics: homeowners are voters, and their largest asset is their home, and much of that asset's value is really land value. Taxing it means taxing the people most likely to show up at planning meetings. The political economy of housing reform is a problem that no amount of economic clarity has yet solved.

Australia: The Case Study

Australia is the housing crisis in its purest form — the pathology with the least disguise. House prices have risen from 2.5 times annual household income in the 1990s to over six times today, a steeper trajectory than even the US or UK. The Australian Housing and Urban Research Institute declared in 2020 that the "Australian dream" of home ownership was no longer "relevant" — the window of post-war affordability that pushed ownership above 70% "has now slammed shut and is unlikely to reopen."⁵

The numbers tell the story. On current trends, fewer than 55% of people born after 1990 will own a house by 40, compared to a historical high of nearly 72%. The proportion of outright owners has shrunk from 40% to 30% in twenty years. And the proportion of owners aged 55-64 still carrying mortgages has tripled, from 14% to 47%. Australian households are now among the most indebted in the world.⁶

What makes Australia especially instructive is that the policy settings are almost comically pro-landlord. Negative gearing lets investors deduct rental losses against other income. A 50% capital gains tax discount, introduced in 1999, encourages speculative buying. First home buyer grants don't make housing cheaper — they fuel demand and push prices higher. Between February and September 2021 alone, the median new mortgage increased by $80,000, more than one-and-a-half times the average annual income. The result is a system where, as one think-tank director put it, "unless you inherit capital, you cannot buy a house."⁶

The political economy is vicious. When Labor tried to reduce housing tax breaks at the 2019 election, they lost. The Property Council vetoed a tiny 1.75% development tax that would have funded social housing. As a result, Australia relies almost entirely on two housing options — private ownership and private renting — while Nordic countries have developed cooperative housing (22% of Swedish housing stock, 40% of Oslo's), "Housing First" approaches that have nearly eliminated homelessness in Finland, and non-speculative public housing models that channel surpluses back into building more.⁵⁷

Finland is the sharpest contrast. It abandoned the assumption that homelessness was caused by personal failings and adopted a "Housing First" policy — house people first, then solve their health and social problems. Between 2016 and 2019, Finland explicitly targeted 3,500 dwellings for homeless or at-risk populations, calculating that housing one long-term homeless person saves roughly €15,000 per year in avoided crisis services. The country now aims to eliminate homelessness entirely. Australia, meanwhile, has 116,427 homeless people — roughly 5 per 1,000 — compared to Finland's 4,542, less than 1 per 1,000.⁵

The deeper lesson is about path dependence. Australia's entire economy has become structured around rising house prices — the value of residential property reached nearly $10 trillion, the mining sector that once drove growth has shrunk to under 7% of GDP, and the financial sector's exposure to mortgages means that any meaningful correction threatens systemic stability.⁸ The country is caught in a trap where the only constituency with the political power to fix housing — homeowners — is the constituency that benefits most from not fixing it. Every proposed reform either stimulates demand (grants and shared-equity schemes) or is politically suicidal (touching negative gearing). The potholes-to-nowhere outcome from Honduras's libertarian experiment has an Australian cousin: a system that optimizes for existing wealth while locking out the next generation.

The Sideways Tug

The housing theorists suggest that the solution needs to be sneaky. Not a top-down rezoning battle, but something that turns the zero-sum game positive-sum. One proposal: allow individual streets to vote on greater density, with existing homeowners sharing directly in the financial value created. No construction where a majority doesn't want it, but enormous incentives to opt in.

Whether that specific mechanism works matters less than the underlying insight: housing shortages may be the single largest drag on Western prosperity, health, and equality. Not in the sense that housing is the only thing that matters, but in the sense that it's a bottleneck that makes every other problem worse. Fix housing supply, and you don't solve inequality or climate change or falling fertility — but you remove the thing that's making all of them harder to solve.
