Think you have the answers to why go where taxes and labor laws cost you more: we also get higher compensation and governmental services. Money well spent.
Recall many many moons ago, one of my friend and colleague sold his CA home and moved East for another well paid job. Ever since, whenever we met in conferences, he would shake his head and said it was a mistake. He was referring to never able to afford the same house again. He was paying less than 4X his salary for the price of his old CA home then. Today, he'll need to pay about 20X assuming a typical salary of $125K a year.
