Prediction: Many lower-paid staff will be outsourced (Think Apple and Foxconn; Think big companies and their outsourced cleaning company).
Currently, typically things like cleaning staff, internal mail, dining get outsourced. Expect customer support to also start getting outsourced. The unfortunate thing is that now there would be a middle-person also collecting a spread from the company/worker (but to the company, the spread will be lower than the tax.)

The talented workforce is there because of the companies. Why would someone deliberately choose to live in San Fran when given the choice of many cleaner, nicer cities with a lower cost of living?

The Silicon Valley wasn't nominated as the tech hub overnight, it became one through an organic process thanks to a mix of good weather, access to capital, a pool of talented employees etc.
Don't take any of that for granted (well except the weather I guess, but with Global Warming and earthquakes who knows).
