Sure, but consider that the majority of people in SF/SV are priced out of the market and are instead renters -- they're getting the worst of both worlds.
The point is that as a non-homeowner, you don't pay property tax so you don't benefit from low property tax rates. Instead you're paying rent that's among the highest in the nation. And your salary, which better be large to deal with the outrageous rent, is being taxed at one one of the highest rates in the country. It's the absolute worst tax situation to be in.
