Compared to costs
We know mainly why costs are too high in the Bay Area, and it's mostly housing. Which is a solvable problem, if only the market was able to expand housing supply.
If only.. there was more land. Building houses is not the bottleneck. Land is. You'd have to create a 'second floor' of land to mitigate the problem.
Or -- stay with me on this -- allow a 'second floor' on top of the current single-floor buildings.
Seriously, NIMBY zoning that doesn't allow for higher-density 5-6-floor townhouse-style development is the issue.
