And even if they did make those promises and honored them, you're taking a risk that they won't. And it's not like you get the FAANG salary back if they can't follow through on working hours, the tech stack, or whatever other consideration is important.
Work from anywhere is a fairly powerful lever. You can reduce taxes and cost of living extensively and still be able to save the same amount of money in the bank and have the same amount discretionary income. I estimate something from a %30-%40 'discount'.
