The solution is to not tolerate drug use, petty crime, vagrancy etc etc Homeless people aren't stupid. They find a way to get to where it is most comfortable to be homeless. In SF you can do drugs all day and night and get free needles and poop on the streets and no one will bother you. In other places you will not be able to do this. Why are people surprised that places that go to great expense to subsidize homelessness have a lot of homeless people?
