LMAO! Nah, Saudi Arabia is just one of the nations accepting bigger piles of American dollars.
I can't believe how many people assume that if we buy something, and we reckon it in dollars, then we must be getting those dollars back in trade. There are three things that do not show up in trade imbalances: Stocks (ownership of American companies; bonds (requires even more dollars later); and real property (of which we will eventually run short.) Granted, a lot of those dollars are changed into other currencies. But since we run huge trade deficits with the world as a whole, obviously those dollars are not coming back in trade.
America is like the farmer making $50K a year and working his ass off. One day someone offers him $5K for a small piece of land. Encouraged, he begins to sell land. Pretty soon he stops farming altogether, since he's making even more money selling land than he ever made farming. But eventually he runs out of land to sell, and he can't return to farming since he's sold all his land, so he's screwed. Once we've sold all our real property and stock, we're screwed. The rents we pay, the profits from our corporations, will flow out of the country. And our iPhones and MP3 players and LCD televisions are really going to need replacing with the latest models. And we're really going to pitch hissy fits.
