The Greeks and Romans tried it. Would that they had been the last.
With the presidential campaign under way, expect to hear a lot more about a shiny new toy of progressive economic thinking, “modern monetary theory.” It seems to be the only intellectual contortion that might allow candidates to promise virtually unlimited government spending without any deleterious effects on America’s currency, standard of living or liberty.
MMT rests on four basic assumptions:
• Because the government has monopoly power over its currency, it doesn’t face the same constraints that households and businesses do.
• Thus the traditional belief that governments must tax and borrow before deciding how much to spend is flawed. Governments can and should spend first to guarantee full employment. They can then decide how much they should tax or borrow, if at all. The central bank can simply enter money into accounts to make up any difference.
• In this sense a government deficit is the equivalent of a private-sector surplus. Greater government spending produces greater personal prosperity.
• Taxes, not interest rates, are the means by which the government would, if necessary, control inflation.
Economics is the study of allocating scarce resources. While it is true that the U.S. can now spend money it doesn’t have, it is also true that if this were a reliable path to prosperity, no country would ever lose its reserve-currency status. The civilizations based in Athens, Rome, Constantinople, Florence, Amsterdam, Madrid and London all learned that painful lesson the hard way.
There is really nothing modern about Modern Monetary Theory. No one running for president in 2020 will tell you this, human nature being what it is, but Washington will overextend its exorbitant privilege too someday. The question is when. Promising unlimited government spending without any concern for how to pay for it will hasten that day.
America currently counts among its many blessings the world’s only true reserve currency
