I don't go to SF unless I have to now. I have no idea why rich people are still flocking to SF. It is only a matter of time before the homeless set up at Broadway and Broderick.
Last time I was there I saw a nice woman driving in a top-line Range Rover with her cute blonde kids in the back. They stopped at an intersection near the Bay Bridge. The underpass was jammed with tents and all manner of desperate people. Some young guy from the camp made eye contact with them and stared them down from a distance...they were oblivious. These people think the invisible wall will hold. I don't want to be in SF the day it breaks down, and I am convinced it will.
The city government isn't liberal enough to raise a local tax to build a solution, but also not conservative enough to take a hard line. They're just letting it fester and it will become worse and worse until someone decides to break through the invisible line separating the tent cities from the Pac Heights mansions.
