The speculative nature of tech start-ups and the tech industry in general are destroying Oakland and they’ve already wreaked SF. The inflated values of companies paying these high salaries combined with no political will to create some sort of plan for the future is going to drive out working people of all backgrounds. There doesn’t seem to be any drive to incubate a future where the whole of S.F. and Oakland maintain the character of each city. What we will have is cites with high rent condo towers and not much else.
