Somehow, the idea that the supply of money must grow perpetually to pay the interest on money debt has found popular support on the Internet and other media. In fact, the quantity of money can remain fixed, as it should, while borrowers continue to pay the interest on their money loans. Even within a fractional reserve banking system—with no commodity money "backing"—the payment of money interest does not generate a need for an ever increasing quantity of money.
With this presentation I will use four simple models to demonstrate how borrowers pay interest on money loans without an increase in the quantity of money. Then I will identify some important economic concepts overlooked by the advocates of this notion of perpetual money growth.
The presentation on the Growth of Money to Pay Interest will not fit this screen. Please open this page on a larger monitor to view the presentation.
Money = Debt: Fiction (& Some Truth)
