That's likely, but not very new; it's been true for several decades at least. We have various economic crises, of which the Great Depression on the 1930s, the stock market crash of 1929 accompanied by runs on banks, and the 2008 bank crisis are examples. And there's a lot that unsustainable, and not just about money. A "fiscal" crisis might be the most graceful, easiest way to fall. A fiscal crisis is plenty bad enough, but (a) g****l w*****g and (b) international injustice are likely to end up coming home to damage us more than any fiscal thing (but will probably take longer to happen).
