The equilibrium for new housing construction will always be "just enough to keep it expensive by local standards [i.e. by local wages]." That's especially true with rising labor, material, and capital costs.

It was actually the post-war housing boom that was abnormal, fueled by aggressive federal funding of suburban buildout. US municipalities are now broadly doomed to bankruptcy trying to maintain sprawling infrastructure that was never cost-effective to create in the first place.

Look at Austin TX. Influx of new building, prices stabilized, and now construction is dropping off a cliff. No one can afford to build into a stable or potentially falling local market. Construction will start again when local productivity grows enough for people to bid the prices back up again.
