I think the most hilarious backlash is the one from folks who moved here barely three years ago. Apparently, if you don't work in tech, you are somehow more of a real person and keeping it real. Bull fucking shit.
The issue is tech-salaries are so high these days, that the once decently priced apartments of SF are now increasing beyond what their non-tech jobs can support. So even the Starbucks employee who moved into SF 2 months ago is always wondering how long he can afford to be there.
I'm not sure a starbucks employee could have afforded to live in SF for the past several years.
