You're making it sound like they are entitled to stay there. Just move to somewhere within your price range.
Things change. Get over it.
Well... the street is a pretty drastic first move. My first suggestion would be "some place you can afford." I've known several people that left the Valley (actually, California entirely) because they were finding it hard to afford stuff.
I moved to Richmond. An engineer I'm friends with just moved to Pleasanton. Why should this well paid people be forced to move out of SF while we're creating low cost housing for artists? How does this make any sense?
