These are not impossible problems. They are fixable and we need to agree on the root cause before we can talk about solutions.
Moving to a city that already has a functioning society is something one person can do without permission. So people do.
They all have something wrong with them, but only SF has it's unique set of problems.
So everyone has to figure out what tradeoff works for them.
To me the biggest flaw in SF is the institutionalized Nimby-ocracy and the resulting housing and homelessness crisis, which I think poisons most areas of society.
Texas seems like it has that side of society figured out. It has other serious problems, I know.
