30 year bay area veteran here.

There is nothing special about the bay area that isn't geography. The density of workers means you meet a ton of talentless people who shuffle along with the crowd and are rewarded for it because it's unnoticed. I'm paid more to be remote than I was in the bay area and my money goes a lot further. I'm also exponentially more productive not being in a sardine can office. Your intuition is shaped by your inexperience of the reality of the situation. The grass isn't greener in my old backyard than it is in my new pasture but I have a lot more of it now.
