So why is there never discussion of reducing demand instead of increasing supply? As in, put a limit on how many employees can be hired in the Bay Area by any company. Google, Apple, Facebook, Netflix, and all the rest bring in many tens of thousands of employees (and their families) every year. They crowd out the nicer apartments, making them unavailable and unaffordable to low-wage employees. And eventually the tech worker cashes in their fantastic stock growth and over-bids on a house, driving prices up.
The suggestion of capping hiring in the Bay Area seems to be a taboo suggestion, not sure why. Seems to me, when your house is flooding from a broken pipe, first thing you do it cut the main.
