Look at all the HNers already complaining they can't afford to live in SF on $150-$200k/yr. Once the [mb]illionaires come in and push them out of places they can afford, it's going to be really hard going on the housekeeping staff and baristas and waitresses in the area.

On the other hand, though, they might finally have enough sway with the local government that they will actually push the homeless problem into someone else's jurisdiction /s
