Study the London G20 communique from April 2, 2009 if you want to really appreciate the hubris of the banking cartel/cult. Also if you haven't heard of quantitative easing after just a little research you'll wonder why.
Funny money was injected into the American economy(quantitative easing) to try and instill a false confidence in us so we wouldn't make a run on the banks. They thought our acceptance of this debt would be the final nail in our coffin. Their whole devious plan was dereailed with the stroke of a pen on December 21, 2017.
