Get this: China sends us all this great stuff, and the only thing they get is OUR FIAT CURRENCY, which is essentially worthless. And then, what do they do with that currency? They buy our treasury bonds, which pay them interest in our own fiat currency. Not only that, but every bond they buy is more encouragement to help us keep the US economy strong and stable. The trade deficit thing looks like a great deal for us when viewed from some angles.
