If so it might well completely collapse the economy.
You say that as if some in power don't see that ideologically as a feature, rather than a bug. Many in positions of power/wealth have set themselves up so that they would benefit hugely in various ways such as politically/ideologically and financially from such a disaster, and in fact use it as a catapult into total authoritarian takeover.
George Soros, as one example, has made a pastime of profiting, and many say working to cause, national currencies and economies to collapse. There are many others who would stand to benefit enormously in various ways both inside and outside the US from it's economic/political collapse.
Bottom up, top down, inside-out.
