Economic storm brewing in America

There's an article in The Telegraph predicting disastrous times ahead for the American -- and hence global -- economy. These kinds of doomsday stories have been doing the rounds since I cannot remember when, but the thing that struck me the most about this one was the very high quality of the comments the story elicited from readers. It almost seems as if any of the insightful commenters could have done a better job of writing the story than the actual author.
