SF city government provides housing for about half of the city's homeless people. The homeless and mentally ill people in SF come from all over USA. You see them SF, but I don't think SF shares much of the blame for their suffering. American voters are to blame, mostly Americans who voted for Republicans who reduced government spending on social services.
Yes, I still know people who blame the Republicans who ran the state in the 70s for the homeless problem. That was 50 years ago, but it still makes a good narrative.
