>> Foreign countries buy US dollars so they can trade with other people. That guarantees the deficit since they give us something in exchange for USD, which they do not then spend on goods we make.

This is called Triffin Dilemma- And in many lies at the core of the most basic question every power in history has faced.

That is- You can either be a Geo Economic Super power or a Geo political Super power, You can't be both at the same. You have to chose to be one. China seems to be chosing the former. USA chose to be the latter, but can't seem to be sure about its choices so far.
