Sorry, I meant housing, which raises base salaries, which makes it hard to do a bootstrapped startup (both one's own living expenses, and hiring first 20 employees requiring market salary to survive)

If you could live comfortably in SF on $30k/yr like you can in a lot of college towns, you'd be able to bootstrap a company for a couple years on just your savings, which would increase the variation in startups -- you could see more genuinely ambitious startups which didn't depend on getting funded.
