Modern Monetory Theory Accounts for Not Causing Hyperinflation

How does modern monetary theory adjust for inflation, even though the U.S. doesn't produce its own money? How do you explain when almost all markets now are tied to global markets? In these global markets are kind of reliant on the neo liberalism that was kind of adapted in the eighties, regan, thatcher era? I think that's pretty much the main point that most people would have some sort of grape with.
