You're easily "shocked", I suppose. I'm not making a moral judgment, I'm pointing out that SF has gone from declining rents to a "crisis" market within a few years' time. The rent crisis is acute, and it's quite obviously due to a bubble on the demand side.

I could have just as easily used 2012 as the year, because rents were more-or-less flat in SF from 2010-2012, after some declines in 2009. Rent lunacy began concurrently with startup valuation lunacy.
