America did not have 200 million naturally-occurring houses that needed to be "filled up". 20th century Americans had to build them all. This is still the obvious and best way to relieve housing costs.
This county owns land which it is going to develop for housing. Their goal? $450k houses because that will bring in more tax revenue than the same number of affordable homes.
Sure but it's a matter of turning some policy knobs, and we know where they are and how much to turn them. The policies that prevent us from building are favorable tax treatment of existing properties and financial penalties for building new ones, favorable treatment of professional labor and penalization of productive labor. The "better options" of which you speak are policy outcomes and we can change the rules.
Clown world indeed.
