If I am not wrong, the money is no longer tied to gold, so printing hundreds of trillions of dollars and distributing to all countries the same and equal amount, and USA dollar would dominate the world currency.
Isn't that similar to what's already happened and helps to explain what got the USA in such a mess?
(And for the picky pedants, I did say 'similar')
I think Frau Merkel has tried this and failed miserably, but its probably our fault because we didn't join the euro.
