That is extremely incorrect analysis. Nationwide homelessness used to be extremely rare and limited to mostly middle aged men and older women. Now in America homelessness has become common everywhere and we have homeless working families which simply didn't happen before. Back in the 1970s minimum wage would support a small family and modest homes were available in most markets. Blaming San Francisco for this major nationwide change makes no sense at all.

As recently as the mid 1970s simply being black or in a homosexual relationship could get you beaten up and thrown in jail. People rejected this arrangement because it was unfair, unreasonable, and extremely expensive. Then the drug war turned the whole nation into a kind of gulag. Go ahead and object to Chinese treatment of minorities, but we have more in jail here.

Neoliberal economists said that if we just lowered taxes enough there would be plenty of opportunity, but modern capitalism runs lean and fires fast. Even basically competent middle aged men can have trouble, so the larger population which includes people of various genders, ages, and capacities is not doing well. Labor markets are as brutal in America now as during the depression. You can't shred labor markets and leave them in tatters and then whine about how society isn't fixing itself like before.

The appeal to dominance and laws and enforcement is a silly delusion that we will have to get over if we ever want to make progress with this problem for real.
