Agree. I actually grew up in the south bay when there were orchards and fields of wild mustard and all. There is this assumption that high tech workers are foreigners or newcomers displacing the locals. It simply isn't true, there are many local residence who work in the industry. We contributed and benefited as much as anyone else.
As I see it, we should focus on solving these issues as residence of the Bay Area as a whole. Pitting one group against another will just deplete the political will necessary to make vital policy changes to allow high density housing, mass public transit, raising minimum wage, improving education, etc.
