I agree with him.
Fiat currency is not the problem. Congress is.
Congress has repeatedly acted irrationally and fiscally irresponsibly.
The FED hasn’t. The Fed has done a remarkable job of keeping inflation low and providing additional liquidity during market downturns.
The only thing the Federal Reserve has done is spread money/credit all over the world at (-)0% rates, banks turn around and try to loan at 4%, 7%, 10% or more while retirees and savers are getting killed on their bank holdings as prices on the shelf continue upwards with at the same time artificially low savings rates.
Adding money/credit into the banking system without the economy responding in kind will eventually come back to bite the banking system, in turn the taxpayers.
