History doesn't support this. Industry dominance tends to concentrate. NYC is still the finance capital of the west. Everyone claims the high costs will drive the industry to migrate to Florida or something but it doesn't happen. Especially when you can just go across the river to Jersey City if you want to live cheaper. SF is expensive but you can still go to Oakland or Alameda or something which is a lot more reasonable than asking someone to move to Idaho for your company.
