Fiat Money

The title says "The Impending Collapse of the World Economy" but the video is mostly about true fiat money (non-debt based), such as tally sticks, the colonial money, and greenbacks issued by Lincoln.  This leads to an interesting thought - are we moving towards that now with Quantitative Easing?  Whatever government bonds purchased by the Fed are interest-free, because the Fed turns that money back over to the Treasury.
