I mean, what makes american so special in their ability to consume? An african can watch football on their 54" TV just as well as an american. Just ship this crap there instead of in the US if you're so concerned about consuming it.
It's trade imbalance! You ship stuff, and the IOUs you get in return are never claimed. It's no better than shipping stuff in Africa and getting Zimbabwean money in return. Everyone knows that it can't be claimed for anything tangible, except from other countries who also owe fealty to the US and are forced to give this currency value. If everyone "asked" for something in return of those IOUs from the US itself, they'd get nothing of tangible value in return. These IOUs only have value insofar as the US is the world police.
