As we pay the national debt, the money becomes available to loan, for Congress funds the bonds and the investors willingly buy them for what Congress pays. Each dollar reduces future bond sales. We can turn that money into accounts receivable, an asset, by loaning it out. A city can avoid a tax increase to cover pension shortfalls or infrastructure expense. They can cover a current shortage by tapping a revolving account at 3%, while they revamp their pension structure. The debt service could well save them money, and once reforms take hold, they can pay it off. Each dollar paid back to the Fund reduces the debt yet more. Once the debt is fully balanced by its accounts receivable, it will be paid off, and the loaned payments will begin to eliminate income tax. Once the loan has been repaid, the city may find itself in a position to cut sales and property taxes.
