Many of our country's problems are reducible, in one way or another, to the fact that we have lost the imperative to transform the physical world. While the soft technology of the internet has marched forward, development of real stuff — of steel and concrete — has slowed, hampered by laws that privilege the status quo.
Many Americans experience the fallout from our failure to build in the housing market. Housing costs are at an all-time high, and over the past half-century, the median rent has outpaced the median household income. In our coastal hubs, our most productive cities, the numbers are even more dire. The typical home value in San Francisco, for instance, is $1.48 million, 12 times the city's median annual household income of around $120,000.
Housing costs exacerbate economic hardship and inequality. Because the poor spend a greater share of their income on housing, high costs hit them the hardest. State homelessness rates track housing prices. The economist Matthew Rognlie showed in 2015 that capital's rising share of income, an indicator of growing inequality, was caused entirely by increases in housing prices. Housing costs also perpetuate educational inequality; they are 2.4 times as high near high-scoring public schools as near low-scoring public schools. Children whose families are priced out of the best school zones forgo hundreds of thousands of dollars of lifetime income as a result.
Although housing is for many of us a proximate manifestation of the failure to build, it is not the only one. America's airports lag those in Asia in Europe, and high-speed rail is practically nonexistent. We have more electric power outages than residents of any other rich country. Our infrastructure inadequacies slow our response to climate change and lower living standards.
The solution to high housing costs could not be simpler: Build more homes. To address housing affordability, many progressives have advocated subsidized affordable housing programs. These programs may not be adequate to generate sustained cost reductions, and they aren't necessary. What will work with certainty are the laws of supply and demand. If we increase the supply of housing enough, prices will fall. Any solution to our infrastructure problems will likewise boil down to the need to build infrastructure.
But to build housing and infrastructure, we must sweep aside the regulatory obstacles that stand in the way.
In housing, zoning and related rules are the culprits behind the restricted supply of new homes. Zoning, in theory, is supposed to separate incompatible uses of land — for example, keeping polluting factories separate from housing. In practice, it has an ugly history of promoting racial segregation. In 1910, Baltimore adopted the country's first explicitly racial zoning law, barring Black residents from moving into predominantly white neighborhoods and, cynically, vice versa. The Baltimore law was copied in cities all over the South until the Supreme Court held that a version in Louisville, Ky., was unconstitutional in 1917. Even after this ruling, explicitly racial zoning codes in some cities tested its limits.
While we would not tolerate open segregationist justifications for zoning today, laws that ban multifamily construction in certain neighborhoods — along with parking minimums and restrictions on lot coverage, setbacks and building heights — continue to perpetuate segregation by income and race. These rules reduce the supply of housing, increasing its cost. Recent research estimates the value of the "zoning tax," the amount by which zoning rules are artificially raising the cost of land. In our coastal hubs — San Francisco, Los Angeles, Seattle and New York — the zoning tax per quarter-acre of land exceeds twice the city's median income. In San Francisco, it's four times the median income.
