HAHAHHAHAHAHAHA — the paper and coins you and everyone else are carrying or storing in vaults are an infinitesimal and meaningless percentage of the actual money supply in this country and indeed, the entire world...
Money is created by banks, currency by governments. And the currency in this country (and the entire world) is backed by nothing more than a pack a bankers and their bought and paid for whores in the government saying “this green paper has value”. Every time a bank shoves a few electrons in the form of a loan or buying a bond from Uncle Sugar, it creates money.
Although it seems the fed creates money out of thin air, it at least has to balance the ledger- this is called buying US bonds (which has always been the mechanism to control the money supply- popular media thinks it is the discount rate). If Trump discounts (renegotiates) the bonds, then the ledger is balanced with a loss by the fed and the money remains in the economy. So you laugh at me, but you made my point.
