The amount of money in circulation around the world barely exceeds 1 trillion USD.
This question has no solution. The debt will never decrease, only increase.
You realize that you just made that up right? The USA GDP is about 14 trillion USD and the world's GDP is roundabout 60 trillion USD. Theoretically, if the USA didn't spend any money at all for a year, then we could pay off the debt entirely, but that is massively implausible.
The question does have a solution, but it is complex and long term and most people don't have that sort of attention span, even when the issue doesn't directly effect them. The debt is a problem because the more debt we have, the less free we are to spend on things that really matter, such as those benefits for the unemployed that everyone keeps mentioning. It's also, as Flaser said, a power problem. As we get further and further into debt, our periodic payments to other countries increase, thus giving them more power over us, which is kind of a big deal to the US.
The debt is kind of an abstract thought to many americans along the lines of "This thing is bad, get rid of it" but there are very few people with the patience to think up or carry out a reasonable plan of action against it.
ONE HUGE PROBLEM with the US is also that politics plays a larger part in our government than actual governing. A president wants to get re-elected so that he can continue carrying out his agenda, but people aren't interested in reasonable, long term solutions, they want results that they can see, and that effect them immediately, or as far as they are concerned, the Gov't failed them. This is why you hear so much noise about the debt without plans or rationales offered, because they want to make the appearance of doing something about it, but since nobody really knows much about the real problems of the issue, they are content with half-commitments and vague promises.
That is a summary of my feelings on the debt.
