>> Is anything getting in the way? > Yes, developers. (Occasionally zoning/historical associations/local laws in places like San Francisco or NYC. But primarily, it's developers) No, it’s primarily zoning.[0][1] To neglect the vast middle of the market is economic insanity. If some developers build only luxury housing, then they’re leaving money on the table; some other developer will build and sell. When Domenico Crolla can sell a pizza for $4,000, that doesn’t mean Pizza Hut stops selling $15 pizzas. In a well-regulated market, somebody will fund and build middle-class housing. The problem is that luxury car-oriented regulation has made practical housing near jobs impossible to build.[2][3][4] Occasionally, hyper-local objections to affordable housing.[5] But primarily, it is misguided regulation.
