In the US the monetary system is legally under the control of the politicians. And I believe it’s that way everywhere in the world.
The Bretton Woods system was a partial gold standard that applied to foreign currency exchange, but the politicians found a way to cheat, so that failed. If you try to use an honest permanent gold standard that backs all currency you won’t have enough gold.
The only long term solution is a currency backed by goods and services combined with a well informed citizenry that holds politicians accountable.
So how much is "enough?"
The entire point is the discipline of being tied to a commodity bankers and politicians can't create at will. Or, if they print notes based on this commodity, there is an ever-present threat their notes (and debt based on it) will collapse when they go too far.
Quibble all you want - but our present system of completely printed money, controlled by bankers and a few politicians, where ever-more debt and printed money are used to replace political will, buy votes, and paper-over failed progressive schemes, WILL blow up, and take America's middle class with it.
