this is only half the story. What people fail to understand is that hyperinflation, where it happened, was never a result of internal policy failures or just of money printing; it was always a result of having debt and other liabilities in another currency they CAN'T print. This was German hyperinflation, which had reparations debt in gold mark and physical goods. this is Zimbabwe, Venezuela, Argentina. The currency they CAN print doesn't serve to buy goods on the world market or pay their external debts.

The US, however, can do that - UNTIL NOW - because the currency the US prints just drains away in the coffers of the world, in world reserves for international trade, as countries buy up dollars to circulate them, often among themselves, to pay for all sorts of goods and resources. (this is the US' free lunch, it produces dollars for nothing and gets all the world's good back; you could also call it a robbery, as it does it by threat of physical force).

The problem isn't the debt service, or the money printing, by itself. It's those things, combined with the fact that the qworld has had enough of being robbed by 850 worldwide bases, jet fighters and aircraft carriers, through their buying of US rtreasuries and denominating goods in dollars. That's the part that will make the currency hyperinflate: the debt and printing PLUS the fact that this printed paper can no longer be dumped on the world for free goods.
