I've never believed in doing something just because everyone else thinks its the default thing to do. Putting 1.5M to 2M into a small average house didn't make sense to me when that is enough money to retire in many different beautiful places in the world.
So I left. Switched jobs and started working remotely. I now live in a MCOL area and things are about 30% cheaper than the Bay Area. Better schools. Nicer environment. More diversity (including economic diversity). More access to activities (like gymnastics) for my kids at a reasonable price. More free time.
I make a little less money in cash. And a lot less money in equity. But all in all its a better life.
I hope more people open their eyes and realize these tech hotspots are actually hell.
