The House That Built America

The house that built the American middle class is still standing. But for a growing share of the country, the door to it has swung shut.

It was, by almost any measure, the greatest wealth-creation machine in American history. Not the stock market, not the bond market, not the 401(k). It was the front door.

In the decades following World War II, buying a house was something an ordinary family could actually do. A returning veteran could get a zero-down-payment loan through the GI Bill. A factory worker, a teacher, or a nurse could qualify for a 30-year mortgage and own a piece of the American landscape. The monthly payment would eat up maybe 12 or 13 cents of every dollar earned. That home would then do something remarkable. It would go up in value, year after year, turning the asset that ordinary families lived in into the primary engine of their wealth.

That era is over. According to the National Association of Realtors, a family earning the median American income can no longer qualify for a mortgage on the median American home. The Housing Affordability Index posted an annual average of 98.2 in 2023, the lowest on record and the first time the yearly average has fallen below 100 since the index began tracking in 1970. It means the typical American family has been priced out of the most reliable wealth-building tool in the country’s economic history. In Minneapolis, the 2040 Comprehensive Plan is trying to do something about it. The intentions are hard to argue with. The results are harder to predict.

The Golden Age Nobody Calls by That Name

According to research from the Federal Reserve, the U.S. homeownership rate rose by 20 percentage points between 1940 and 1960, the largest such jump in American history. As HUD documents, it climbed from 43.6 percent to 61.9 percent, driven by government-backed mortgage insurance, a booming postwar economy, and a deliberate federal commitment to turning renters into owners.

The price of a median home in 1950 was about $7,400. The median household income was about $3,000. By 1960, as the 30-year fixed mortgage became standard, monthly payments consumed between 11 and 16 percent of income, well inside the 25 percent threshold that financial planners consider the boundary of affordability. That same 1950 home was worth over $17,000 by 1970. Financed with a small down payment, it represented an extraordinary return for a working-class family. The house was not just shelter. It was, quietly, the most powerful financial instrument available to ordinary Americans.

When the Math Stopped Working

In 1981, mortgage rates hit 18.6 percent. Monthly payments became crushing. Rates eventually came down, but prices kept climbing. By the early 2000s, lenders had found a workaround: if borrowers could not truly afford the homes they wanted, banks would simply lower their standards. Adjustable-rate mortgages, interest-only loans, and no-documentation underwriting all became common tools for keeping the dream of ownership alive. Then 2008 arrived.

The foreclosure wave hit Black and Latino families with particular force. As the Urban Institute has documented, Black homebuyers had purchased at peak prices at higher rates than white buyers and were disproportionately targeted by subprime lenders pushing risky products on borrowers who qualified for conventional loans. The equity they had spent years building evaporated. The Bipartisan Policy Center reports that home prices have surged 50 percent since 2020, and the salary needed to afford a median home has risen more than 78 percent in that period.

Who Was Left Out from the Start

There is a version of the post-war housing story that leaves out roughly a third of the country. The FHA, the agency that made the boom possible, also underwrote racial segregation. Its guidelines actively discouraged lending in mixed neighborhoods, and it refused to insure mortgages in Black communities in city after city. VA loan programs were administered locally across the South, where Black veterans were routinely denied benefits their white counterparts received. The GI Bill created a generation of white middle-class homeowners. For Black veterans, it was often just a piece of paper.

The numbers from that era carry forward. As the Urban Institute has shown, the gap between Black and white homeownership rates is wider today than it was in 1960, when it was still legal to refuse to sell a home based on race. Wealth not accumulated in the 1950s was not passed down in the 1970s or the 1990s. Minneapolis is a concentrated example: Urban Institute research finds that among the 105 metro areas with significant Black populations, Minneapolis-St. Paul has the largest Black-white homeownership gap in the country, at 51 percentage points. According to the National League of Cities, Black and Hispanic homeowners derive a higher share of their total wealth from their homes than white households do. The exclusion of those families from homeownership is not just a measure of inequality. It is the mechanism through which inequality is reproduced, household by household and generation by generation.

Minneapolis Tries Something Radical

The Minneapolis 2040 Comprehensive Plan emerged from a city where rents had climbed sharply, lower-income residents were being pushed out, and the racial homeownership gap was the worst in the country. The solution: eliminate single-family zoning everywhere in the city. Every lot previously restricted to a single house could now host a duplex or triplex. The logic was that more units mean more supply, and more supply should moderate prices. Opening up the most expensive neighborhoods could give lower-income families access to places that had effectively been off limits for decades.

The political courage required to actually do this deserves acknowledgment. But good intentions embedded in a complex market do not guarantee good outcomes. New housing in high-demand neighborhoods is expensive to build. The duplexes and triplexes Minneapolis 2040 was meant to produce are landing, by and large, at price points that work for households already doing well, not for lower-income first-generation buyers.

There is also the upzoning effect on land values. The moment a parcel becomes legally developable at higher density, its market value rises before a single nail is driven. Property owners start pricing their land at redevelopment value. That pushes up assessed values, property taxes, and rents, accelerating the displacement of exactly the tenants the policy was meant to protect. And new affordable supply takes years to arrive. The families displaced in the gap do not get to wait for the long-run benefits.

What Would Actually Help

None of this argues for doing nothing. The post-war housing boom worked because it combined supply with subsidy. The FHA and VA did not just allow more housing to be built. They made specific financing tools available at prices ordinary people could afford. The 30-year fixed mortgage with a government guarantee was not a market product. It was a policy instrument. And it transformed the economic landscape of the country for a generation.

Reversing the current crisis requires comparable ambition: community land trusts that remove land from the speculative market, down payment assistance targeted at first-generation buyers, and subsidized construction priced below what the private market will deliver. The Urban Institute points to special purpose credit programs as one of the more promising tools for closing the racial homeownership gap, allowing lenders to extend credit on more favorable terms to historically excluded groups. Zoning reform alone cannot do that work.

The Minneapolis 2040 plan is serious and well-intentioned. What it has not yet done is pair supply-side reform with the demand-side interventions that would make new housing actually reach the people who need it most. The history of American housing policy suggests that the distance between making room for more housing and making housing that working families can afford is exactly where well-intentioned reforms go to stall.

The house that built the American middle class is still standing. But for a growing share of the country, the door to it has swung shut.
