This animated 45-minute documentary explains how what we now know as money was created, and it explains how the fractional reserve banking system that's evolved now props up and controls entire economies by encouraging and ensuring debt; it also suggests the need for reforms to this system. Your notions about work, the value of a dollar, and the banking system will be irreparably changed after you've viewed this.
Producer Paul Grignon says of it:
Money created as interest-bearing bank credit is a magic trick, a fraud - now 3 centuries old; one that very few people have seen through despite, or rather because of, its utter simplicity.
It is my intention to make this mysterious debt-money system comprehensible to everyone. It is also my intention to foster sufficient understanding of the problems with this money system that citizens will be motivated to join the monetary reform movement and/or create local alternatives to the global monetary system - a system in which most of the productive people of the world are collectively chained to an ever-increasing and perpetually unpayable debt.
