It sure is in my neighborhood. The Rent Really Is Too Damn High.
Government policies keep it that way:
The inner-ring suburbs around a major city collectively have a much greater area than the city itself. Hence, even modest reductions in density regulations in these areas--replacing large lots with small ones, single-family homes with townhouses--would have a larger effect on the housing supply than allowing a few more 50-story apartment towers downtown.
Matt points out that housing deregulation would have a number of benefits. High-density living is better for the environment. It promotes a more diverse and efficient service sector. It makes reliable and convenient mass transit feasible. But I think the most important message of Matt's book, and others like Ryan Avent's The Gated City, is that it makes clear that astronomical rents are a result of specific regulatory decisions, not an inevitable malady of urban life.
