I live far below my means and save a ton of money. I do it partly for moments like this. If my employer comes to me tomorrow and says "we need you to move to X city/country or else we have to let you go" or "we are eliminating your position, sign this deal that makes you available for 2 years" or any other exploitative ultimatum, I can call their bluff without fear for my own well-being. If more people lived that way, this sort of thing wouldn't happen.
