Also, a lot of "tech kids" like myself aren't in SF proper and thus can't vote on things like SF rent control. It's amazing how privilege acts to protect itself.
Remember that SF is an anomaly. Generally it's the wealthy in the suburbs and the underprivileged in the city. Suburbanites voting on urban policy (in general) is the last thing you should support if you are concerned about privilege.
It's not an anomaly, it's a trend.
That's why rent in Manhattan is so cheap.
Consider the entire middle of the country.
