I’ve read it before. It’s conspiracy nonsense promulgated by people ignorant of basic facts like what US Notes were, and of how the Triffin Dilemma created the pressure to abandon silver certificates and coinage. It’s entertaining but ultimately stupid, as most conspiracy stories are. Kennedy was famously so indifferent to the Fed that he could only remember that they dealt with monetary policy by the coincidence that monetary and William McChesney Martin both started with the letter ‘M’.
From what you write, may I assume that you would want the Federal Reserve to be audited? Transparency would put an end to a lot of “conspiracy theories”, after all.
