I am not saying we should force companies to move headquarters, I am just pointing out that Silicon Valley has huge, one might claim unreasonable, concentration of wealth. This concentration of wealth really shifts perceptions. For instance, 4 years ago or so I visited a friend in SF. We were to meet in a restaurant. An Uber car pulled out and he got out. I asked him about how it worked. His reply: "It's awesome, I order it on my phone, it picked me up and dropped me off here (~3 miles away) for ONLY $40! Isn't that awesome!" I am sorry, but for me at the time $40 was a lot of money, I would have walked the damn 3 miles for that money.
My point is, sometimes I think the entire Silicon Vally is in the bubble of affluence, and might be slightly delusional about what other people, outside the bubble, might think is or is not reasonable. The solution isn't giving the poor people free money, the solution might be to grow (geographically) and spread the bubble around, making lot's of people better off by reducing housing strain in the valley, and economically improving other communities throughout CA or even the grater USA. Just an idea, I might be wrong.
