Today we examine two propositions: (a) 100-percent reserve banking; and (b) national government spending without taxation and debt issuance. Believe it or not the two propositions have been related in the debates over many years. Modern monetary theory (MMT) is agnostic to the first proposition although individuals within the paradigm have diverging views. However in the case of the second proposition it is central to MMT that a currency-issuing government has no revenue-constraint and should not issue debt to match net spending. Further, taxation is an effective tool for attenuating overall agggregate demand rather than raising revenue for a government that can spend regardless.
