I'm assuming you're talking about people born in SF? Because the rest have already demonstrated a willingness to give up their community once in the pursuit of quality of life.

Equally, if you are in SF you're about to feel the pain you've caused to the locals by moving there. Somewhat harshly, I could suggest that you didn't care about their existing community when you priced them out of their neighborhoods.

So here's the rub. SF is somewhat different. It is a company town. If you don't work for the company you're moving. Sorry. There's certainly nothing else that can pay you the same money.

On the up side, there are lots send lots of cheaper places to live. And chances are you can find a good job there doing something that adds value to that community.
