That's ridiculous. Debt = dollar demand, and all "printing" (at least in the US system) is really issuance of more debt. Good luck with your hyperinflation dreams.
Yes indeed. That debt has to be "bought" or rolled over: someone somewhere has to finance this ponzi. Peter Schiff was just on RT talking about the very same.
I don't know if there will actually be a hyperinflation of the USD, but recent trends make that a more likely outcome (doesn't mean it will happen though; predicting a high but not unsustainable Argentina-like inflation might be more realistic).
