The US does export some goods but their value is much lower than the goods that the USA imports, we export movies, McDonald's, airplanes, military equipment. Still there is an wide open 800 Billion Dollar deficit. If you really think the USA is on solid economic ground, think again. People are going to blame Bush, they will probably blame the NeoCons of course, but the real blame has to go to the lavish habits of the American people that have shaped the global economy into what it is today. Much of the developing world manufactures(even much of Europe and Japan lives below their means too) our products and they live way below their means and we live way above ours, something is going to give in a system like that and it already is just happening that way.
The fact is that we now depend on OPEC(Saudi Arabia and company), China, and Japan to prop up our financial system, all three still do that, but its only a matter of time before they stop.
When I was a wee toddler, the USA's standing in the world was pretty much unchallenged. My mom told me in those days, no in their right mind would buy a Honda or a Toyota, in fact those automobiles were among the worst buys compared to Chevy's and Buicks. Today no consumer in their right mind would pick a Chevy over a Honda. We see this across the board as Americans have a penchant for buying more high quality imported manufactured goods, we let our manufacturing base disappear. In the 90s we built the IT industry but now India is pretty much going to own that sector. I actually know what I am talking about with regards to IT I spent nearly a decade in this line of work and a lot of my friends have lost jobs because of outsourcing.
I think though that things can turn around dramatically but the next two decades will be pivotal for the US to take decisive action, it will be make or break time.
