This country is already collapse thanks to so much stuff going on in the rest of the world, we need to help with it just somehow wether we have something to do with it or not.
Anyway, if the US literally collapsed and turned into an urban wasteland, then I wouldnt care. I would move away, definately, if I got the chance. But if I couldnt, I would just grab guns and kill anyone that comes within 30 feet of me unless I trust them.
