I was born in San Francisco. There are some parts of the city-- downtown parts in particular-- that have demonstrably worse homeless problems then they used to for reasons people will disagree about. However, in the eighties the city was also unsafe in many places that are completely gentrified now. There are parts of the city where you would get robbed walking though that are now completely nice and safe, or you would maybe see a mentally ill homeless person as opposed to a crime inclined teen, perhaps armed. The idea that there was a time when the town did not have crime problems seems strange to me.
