So I could retire to SF and get free housing? Count me in.
Sure! Only thing, is that it's first come, first served getting into the homeless shelters at night. Hundreds allowed in, thousands turned away. SF rolls out the welcome mat to homeless and illegals from everywhere, but the reality is that only the rich can afford to actually move into the city. Unless you have been there for decades, you can't get your foot into the door of property unless you can afford several thousands of dollars for monthly rent, or outright buy property for a million or more. Many districts have property values going up 10 percent a year, and rent increases that mirror the situation as rent control allows.
People running city government are idiots, but we all know that. No space to build new housing with an invitation for poor to come in is a fiasco. Cheaper housing is available miles away in surrounding towns, but poor people can't commute so they live in the parks or on the streets. We need a return of vagrancy laws; you can't afford to stay, then move on to elsewhere.
