I see no evidence that H-1Bs are destroying the local talent pool in SF. I can't speak to LA myself, but from what I hear it's not doing that either.
H-1Bs aren't the reason you've think you've "ruined [your] life being a coder in Los Angeles". Your profile has you down as an Android developer: I met a co-founder based in LA last week who was bemoaning the lack of good mobile app talent. I frequently get hit up from startups in LA, and I used to consult for a major firm in the OC that's vacuuming up Android devs. I can't tell you why you're having such a hard time, and I feel for you: but blaming H-1Bs isn't productive.
