So, you want to understand how the Federal Reserve works? Here is the best video on the topic. It was produced by the Mises Institute. It covers central banking’s history.
Unlike other videos on the Federal Reserve, it does not recommend that money creation be turned over to Congress, which will then produce “safe, reliable” fiat money: Greenbacks, or U.S. notes. To imagine that Congress would not counterfeit money by the barrel is silly. Why should anyone trust Congress with a printing press — a true license to steal?
