Bay Area real estate is a shitshow in many perspectives. The root problem is that the money people are all there, and would rather not travel. It’s dumb for all stakeholders, corporate, capital and working that such an important and large component of the US economy is dependent on the Bay Area. It’s doubly stupid as the whole region could be leveled by an earthquake at any time.
