China uses dollars as its reserve currency for its banking system, and it only acquires dollars by giving us real stuff for our printed money.What if one of the major nations you are paying interest to becomes an aggressor and uses the money as a tool to control your foreign policy? The 'I'll stop loaning you money if...' Remember Hillary going over to China with a big smile and kissing up to the politburo, or whatever they call it there? Usually if you go to your banker they want interest, but if your creditor has you by the short hairs they might want a bit more... So what did Hillary give?
Basically, we aren't borrowing Chinese money. We're borrowing our own money that we print and give them.
But borrowing is too strong a term: we print dollars, buy their stuff, then with their dollars they buy treasury bonds. Aka, they convert their dollars into a different kind of dollars (slightly more interest, way better insured). The best analogy I've seen (and it's almost literal) is that fed-note dollars aka cash is effectively a checkings account and t-bills aka bonds is a savings account, both accounts via the Federal Reserve. So their exports turn into cash (checkings) which they swap into bonds (savings). They already own their money one form or another so it's not debt like a loan.
Their having $1 trillion in reserves however makes their money good to other countries, and gives them therefore access to our technology. Pretty win-win.
Not sure how they get to control us with it though, you'll have to explain that one to me, CavLancer.
