Most of us actually exert very little influence in local politics, precisely because we're here for the work. I'm in a tiny minority that's decided to "settle down" and not retreat "back home" once I've got a quarter million in investments and another 100k in cash.
And in fact, I think very few of my peers are super into local politics. Even I'm guilty of being somewhat disengaged until recently, and I'm trying to make up for that now in Daly City.
The property owners moving in sync are what dominate a lot of features in this town, and very few "hackers from this site" are actually in that club. Even the rare post-exit folks like me. The truth is that they have a lot more to gain by keeping the status quo than itinerant tech workers have to lose by just leaving rather than dealing with the difficult problem of entrenched NIMBYism.
I'm dealing with that now in my area and it is AGONIZING to sit there listening to some old man or woman go on about how Asians and Brazilians ruining the community and stealing their parking when they're the ones renting out 3 homes in the first place.
It's true though, if more of us went to local government sessions, we could probably just utterly dominate the discourse and reject a lot of NIMBYisms outright, and that'd probably result in a lot of political changes.
I myself regret bitterly how much I let my parent's culture influence my opinions on this, and it's only as I get older that I fully appreciate the many toxic and counter-productive ways my fundamental christian socialization has influenced me even as I've struggled to move more left throughout the course of my life.
