We're not in China where the Government can decide to do whatever it wants. People in the community will vote on issues and elect officials into office who they think serve their interests. It is a common attitude of "I'd rather have no housing than more housing for people like them". Despite all the media the majority of people in Bay Area communities don't work in tech.

My landlord actively seeks people from the Bay Area to rent to and if they're not from here they're going to pay more rent especially if they work in tech. You're paying the tech transplant tax.
