The problem isn't "solved." The problem is you have to deal with it in a way that most/everyone would be OK with and vote for. I don't think we can do that in the US.
We could "solve" the problem like Singapore or China (some of these 'many countries'), and simply throw everyone in jail for petty crimes. In fact, IIRC Singapore is one of the safest places on earth. I'm sure SF (and California, and the country at large) would probably take issue with a sudden step up in policing.
