That's what happens when you don't allow population density to grow to its equilibrium state. An overpriced, congested city, with absolutely no culture, as the only people who can justify living in SF are basically engineers, designers, and marketing people at tech companies. People living on a dime trying to do something interesting (art, tech, music, ...) is what gives cities their characters. When you take that away, you get a homogeneous group of people making between 100k and 200k a year who think about nothing other than money.
