In answer to the question, No boby knows, because the US has loaned so much money out, over the last 40 years to 3rd countries and countries who were close to going broke (Economic Aid) and so forth that it would take a bank of computers ten years just to calculate the interest due that the princal will never be paid back. That does include the under the table deals and close door deals that are made every year with new countries.

And the reason they do it?

Who else is going to do it?

I'm not sure why you are interested in all this, (school, a future job in Economics, whatever) But looking for answer to some questions, won't be found on a boxing website, even one that has me on it. (Little Joke)

PS. excuse any spelling mistakes. Been up sinse 4am and it has been a looong day.
