its never getting paid off, not in the same purchasing power at least.
the best way out would be to default like Argentina but the American government is probably too proud to admit America is a deadbeat and can never repay its debts.
so whats going to happen is the federal reserve will print as much money as will be needed to service the debt and kill the dollar.
I thought QE had finished.
Will they resume QE in the near future or are they printing behind closed doors in secret so to speak?
The way I see things is soon there WILL be a monetary disaster. This may come in the form of a black swan event or a bank failure leading to a domino effect. All this money that has been printed from QE1,2,and 3 will have to go somewhere and once panic hits a lot of money will be put in commodities like metals and potentially bitcoin if the "man on the street" knows about it and knows how to acquire btc.
It's not just the U.S that have been printing of course. We've been at it here too as well as many other countries!
Just my opinion as a UK spectator.
