Tech in SFBA reminds me of the Resource curse ( https://en.wikipedia.org/wiki/Resource_curse ). SFBA did nothing special to attract the wealth of technology companies, they effectively got lucky with Shockley/Fairchild/Traitorous 8 and the boom in technology that followed. It seems the local gov't have squandered an opportunity to truly capitalize on the gift they were given, and perhaps even done their best to jeopa…
Wait, what?
What exactly was local government supposed to do with this, ah gift?
From the perspective of someone who doesn't live in the Bay area, it is a libertarian paradise for the haves, unlivable for the have-nots, and is the pinnacle of American culture, with its focus on individualistic solutions (detached housing, strong zoning laws that protect existing landowners, reliance on personal vehicle ownership, privatization of critical services) to society-scale problems.
Throw in conflicting interests of the residents of the cities that make up the SFBA, and you pretty much get what one would expect.
Before asking why your local government has not fixed , you may want to instead ask 'Why haven't we elected a local government that would fix that problem?' Tech has an outsized amount of political influence on governments and elections in the area. Governments don't exist in a vacuum, completely detached from the desires of their constituents.
