Once the world stops using U.S. dollars as the worlds reserve currency, the super super rich will be in the same boat as us if they haven't converted their currency into something other then dollars.
Shits already starting to happen. China, Russia and France met in secret to discuss a change of currency already. Many places won't accept the U.S dollar anymore. Even parts of our own U.S!! (Google the berkshare)
If u think shit is tough with 3-4 dollars a gallon, wait till we get like germany or japan and start paying 7-8 dollars a gallon. Since we are the worlds reserve currency, we can simply print more money to pay off our debt. In the long run, it devalues our dollar and as a result other countries will see the weakening dollar as a sign to abandon ship.
Real talk, if you taxed 100% of americans 100% of their income, we still wouldnt have enough to cover even the INTEREST on these loans we are receiving. So IMO the collapse of our economy is what is going to set off a revolution, but the revolution will only be a cover for a resource and land grab.
