Maybe I'm far more mobile than others, but I'm really surprised that there isn't a wave of people trying to poach childless engineers into moving 1-4 hours out of SF to set up shop. Reno, in particular - it's 4 hours out, has actually reasonable real estate prices, and no state income tax. Maybe getting funding requires the VCs to make the trip to your office, and you're not able to just have your leadership make the trip out to SF?
