More dollars chasing the same amount of goods equals inflation. Should the artificial demand for dollars come to an end, there will be a massive increase in dollars and an equally massive deceease in the demand for them. That equals hyperinflation- Weimar Republic time. The fact that we would also no longer be able to print money to buy oil would also suck I think.
There is trivial inflation. Maybe deflation.
Inflation would make the USA purchase fewer foreign goods.
To you, that’s a bad thing. Your view is either idiotic or traitorous, your pick.
