This is a relatively old story based on a paper posted by the Federal Reserve of St. Louis. But it’s certainly something to read and mull over on a slow Sunday afternoon.

The only thing keeping the U.S. afloat right now is the temporary willingness of Asian countries to keep buying U.S. debt, thereby pumping up the U.S. economy with dollars earned on the backs of Chinese laborers.

But even the Chinese — known for their tolerance of hard times and manual labor — may eventually tire of lending money to a posh, arrogant Western nation that has all but abandoned the concept of saving money. Says Kotlikoff, “China is saving so much that it’s running a current account surplus. Not only is China supplying capital to the rest of the world, it’s increasingly doing so via direct investment. The question for the United States is whether China will tire of investing only indirectly in our country and begin to sell its dollar-denominated reserves. Doing so could have spectacularly bad implications for the value of the dollar and the level of U.S. interest rates.”

The American people, as usual, remain oblivious to the financial future that awaits them. Even as the housing bubble is now beginning to burst in the nation’s most overpriced real estate markets, most people don’t have a clue what “hard times” really means. To today’s debt-ridden yuppie spenders, “hard times” means shuffling six different credit card accounts to cover the payments on an overpriced house, two new SUVs in the driveway and a vacation to Paris, none of which the yuppie couple can afford.

The idea of ever having to pay back their debt and live within their means is as foreign to most Americans as it is their own government.
