I think the thing is, instead of the Treasury paying interest to a private bank (the Fed) on the national debt, in future we will be paying it to ourselves, essentially canceling it out. It’s the INTEREST on the National Debt that has been crippling our budget. Since currently ALL money is debt, the national debt = the money supply, and it’s only ever gone up.
The federal budget this year will probably be about $10 trillion. We either have to borrow it or create (priint/digitize) it. That did not work well in the German Weimar Republic.
