Having dollar being the worlds currency is not necessarily a good thing. Yes, you can borrow at low interests rate for a while. But guess what? Those are still debts. And eventually rates rise due to inflation. Now you have hollowed out your industrial base and you are stuck with tons of debts.

Inflation and the "hollowing of your industrial base" are not inevitably connected, and in the case of the USA, have almost no connection to each other at all.
