The Eleventh Marble
Any five-year old child knows that if you put ten marbles into a tin can, you can only take ten marbles back out. No amount of wishful thinking, dreaming, or praying, will yield that eleventh marble from inside that can. That eleventh marble does not exist. It never did, and it never will. All discussions about the eleventh marble are the product of imagination. The eleventh marble is a fantasy.

Private central bankers issuing the public currency as interest-bearing loans operate on the belief that they can put ten marbles (dollars) into a tin can (the world) and magically get 11 marbles back out.
