Good luck paying off 16 trillion dollars.
Yes. That is $141,638 per tax payer, or $51,603 per citizen.
Doubt people would donate that much, never mind have that much to spare.
And if it was added to taxes? Well...
You could make a movement instead to:
Try a resource based economy, get rid of money and trade in resources, rather than the current monetary system.
Get rid of oil, gas and coal stop killing people in the middle east over oil, and use renewable energy which is... wait for it... FREE for you and the environment! (once put in place and maintained).
Or just join the Occupy Movement, support The Zeitgeist Movement, Anonymous and The Venus Project.
Read up on other ideologies, I recommend the communist manifesto and TZM facebook page recommends books all the time :)
