National Debt in the US

Saw a post in a thread, figured this was divergent enough to warrant a new thread.

So, here is the question:

Who the hell do we owe money to, and how the fuck did we spend so much.

Please no 'lol, republicans.  And you can't blame the war for ALL of it (okay 100 BILLION dollars is a bit extreme, but hey, we want the shiny bombs!) so... what did we spend all that money on?

Was it for the fatass who lives three houses down from me who has never had a job but somehow manages to scrounge up enough money to play WOW all day?

Was it to pour the shitty street that I have to drive down everyday to get to work that made of fail and shit?

Or was it to violate my civil liberties via the Patriot Act?

Maybe it was to house the bastards who won't stop smoking pot and 'getting clean' only to 'get high' the next week??!?!

Can someone please explain to me why the UNITED STATES OF AMERICA is in debt?  We are the 'most powerful nation in the world' so, who had the economy to GIVE us money??

Or is this part of the international banking scheme that no one is supposed to know about?

We could just pretend the debt never existed and never pay the Chinese a penny. They'll probably forget about it.
