Prediction: we're going to find out (eventually) that Fort Knox does not have *nearly* the gold it claims to have. People will start to question what the Federal Reserve Bank actually does, and what value a Federal Reserve Note actually has. The US Federal Government uses the opportunity to kill the so-called Federal Reserve Bank and take back direct control of monetary policy for the US Dollar.
After all that, the dollar still fails.
The only question in my mind is "when?" I think there is a 25% chance it happens this year. 95% in twenty years.
Happy to hear why I'm wrong.
