If the central bank is abolished, the treasury system would try to carry on the same function.
Bankers would have no problem ‘swimming’ in either arrangement, but would prefer to keep the Federal Reserve System as it is.
Which is understandable because they know the current system, and have only read of heard about a financial system without a central bank.
Take any note out of your bill fold and take close look at what it says: federal reserve note. There is nothing behind that bill. No gold, no silver, nothing but air.
