And the salary increases are driven by real estate prices. I'm currently on ~$120k/year and I calculated that I would need $200k/year in the valley in order to have an equivalent lifestyle!
I'm not going to uproot my entire family for an equivalent lifestyle so realistically I wouldn't move for less than $240k/year.
I'm not saying I'm worth that kind of money; I'm just saying it's not worthwhile for me to work in the valley for less.
