Is the U.S. Government Insolvent?

From Fool.com

Unfortunately, the government's overheated spending, relying on future revenues and of course, that of future generations, reminds me a little too much of the Ponzi scheme mentality. And if entrepreneurship and business suffers, then our economy will be awfully close to a Ponzi scheme, where money is simply handed around without any real productive enterprise going on. Only this time it's going to include ugly side effects like worthless greenbacks resulting from out-of-control inflation. (And the Fed's $1 trillion move yesterday certainly stirs up still more concerns about runaway inflation even if the stock market did rise on the news.)

And of course, things could most certainly get far worse from there.

I know this sounds harsh, but I'm a proponent of trying to recognize the truth instead of fighting to stay in a state of overly optimistic delusion. I'm not stuffing cash in my mattress or giving up on the idea of investing; I try to remind myself that panic is destructive, not constructive, and won't help our current situation.
