Paul Krugman is totally ignorant about economics and a corrupt human being, the nobel prize goes to those that lick the king's balls. Check this: https://www.usdebtclock.org/ The problem is if many people get destroyed without saving and a job, there will be a lot of poverty around, and now USA is mostly importing a lot of goods from abroad and producing only a few, exporting big tech stuff and dollars. When that system collapse americans wll have to start producing again to trade with bitcoin/gold and whatever it won't be easy. It comes to my mind a mexican working in a factory while there a fat american over 100kg who does not have a job and would only work for 5x the salary of the mexican.
