I agree. Auditing the Fed is a big deal. Even anti-wall street warrior Fauxcohontas Warren doesn't want to audit the Fed.
The Fed, with ex-nihilo creation of money, and charging US citizens rent for using "their" money, and manipulation of interest rates is an affront to freedom and honesty.
Same with the communist Sanders. Of course, Leftist still want full political, centralized control and planning of the money supply. They want the central bank to have even more power - its just that they just want it all for themselves and the state, and want Wall Street cut out of the deal.
How much does the Fed charge you? Do you mail them a check? If you hold two $20s, do they charge you twice as much as if you only hold one?
