No offense, but your statement reflects a complete ignorance in world economics. No offense, because your statement reflects the same ignorance I had a few years ago.

The 20 trillion debt is absolutely nothing, and since we are on a fiat currency our engine actually runs best on high debt. The problem is what's happening with our 175++ TRILLION dollar unfunded liabilities. Let that number sink in!!

Next, remember Greece collapsing? No ATM, s, no paychecks, no banks open, and the few times a month a bank did open, they would only release a few dollars per customer. A $4,000 dollar paycheck would only yield a few hundred dollars.
Now ask yourself, of the imports that Greece received from American businesses, do you think they increased, or decreased? Ok, rhetorical question.
Now imagine all of Europe, South America, Asia collapsing. What would that do to American exports? What would that do to earnings from businesses that Import?
Did you know the wheels are turning and not beginning to turn, but have been towards economic collapse of Europe. ...and it's already to late to stop it, and the real problem no one knows how. Same with South America and many Asian countries.

What do you understand about the Petri dollar?
What do you know about Russia and China signing an agreement to not use the Petroleum Dollar and fade into their currency.
What do you know about the Agreement signed with Saudi Arabia in 1973 to only accept the petroleum dollar, but know they have broken that agreement and even the U.K. along with dozens of other small countries have jumped on the Russia /China train.
What do you know about the international bank China has begun with plans to replace nations around the world to exit the Fed and use them?
What do you think this will do to America's economy if nations wheen of our Fed Reserve sell off T-Bills ? It's already begun, did you know that.
Ignorance unless termed as an insult is not a bad thing when considering the amount of knowledge in our world every human is "ignorant " of a great deal.
A great non-political economic site, with the highest accuracy of anyone economically in America's, history.
