Since we all need to know about the left's latest wizard wheeze, Modern Monetary Theory (MMT), it's time to make sure we understand it and put it in the context of government finance in general and how government finance developed in history.
I understand the historical progress of government finance as follows:
Stage One: Physical Collection. This occurred in the days before Italian banks. Governments collected tribute in grain and silver from their feudal vassals, and the vassals collected the same from their underlings. But the king was always short of money. Always. Of course, if the king were conquering another country then he and his soldiers would loot and plunder the country to the bare walls. The Roman Empire ruled the world for centuries on this plan.
Stage Two: Italian Bankers. By the time of England's Edward III (reigned 1327-1377) a European monarch could borrow money for his military adventures from the leading bankers in the world: Italian bankers. Pity that Edward defaulted on his loans, and all. Maybe that's why the Brits lost the Hundred Years War and have had a soft spot for the Italians ever since.
Stage Three: Dutch Finance. In their war of independence from Spain the Dutch invented the central bank, the Exchange Bank of Amsterdam, to finance the war. It worked so well that they exported their idea and their regime to Britain and the British used the idea to win the Second Hundred Years War against the French at the Battle of Waterloo in 1815. The beauty of Dutch Finance is that enables the rulers to loot and plunder using the indirect method, partly through seigniorage and partly by the advantage of having its debt as the foundation of the banking system. In the 20th century the various nations used central banking and unlimited debt to fight two world wars. They could do this because they could use money printing and debt to loot their countries to the bare walls without the people rebelling.
Stage Three and a Half: Hamilton Economics. Alexander Hamilton, first US Secretary of the Treasury, ignited an economic boom when he determined to honor the war debt of the various states in the Union at par, and service the debt with new federal taxes.
Stage Three and Three Quarters: Bagehot Economics. After the Crash of 1873 Walter Bagehot in Lombard Street proposed that in the case of a credit collapse the government's central bank should act as "lender of last resort" to keep the financial system alive.
Stage Four: Keynesian Economics. After the cock-up of the Great Depression western political leaders needed a real simple strategy (like in The Manchurian Candidate) to know what to do when the economy was wrecked by a financial crash. The strategy was spend and borrow and elect, preferably with a genius like Lord Keynes in charge.
Stage Five: Bretton-Wood Economics. A big problem in the aftermath of wars conducted under Dutch Finance was "resumption," the attempt to return the value of a national currency to its pre-war value after the monetary inflation of war. After the Napoleonic Wars, the US Civil War, and World War I this resulted in "deflation" and social unrest, and usually a big credit crisis. So, after World War II the US did not resume gold payments at the pre-war level while pretending the value of the dollar was still $35 per ounce. The pretense of $35 per ounce was abandoned in 1971 by President Nixon at Camp David.
Stage Six: Supply-side Economics. After the cock-up of the inflationary 1970s politicians needed a real simple strategy to know what to do when Keynesian Economics wasn't working. The idea was to think about what government taxing and regulation was doing to actors in the economy. Maybe high marginal taxes on the rich wasn't a good idea. Notice the cunning in this strategy. It doesn't attempt to deal with the real problem, the loot and plunder of entitlement programs, but attempts some fine-tuning of the loot collection game in order to restore the economy after the stupidity of a Keynesian episode.
Stage Seven: Modern Monetary Theory (MMT). After the cock-up of the 2006-08 Great Recession -- caused by under-collateralized and non-performing home loans and a sub-standard recovery -- politicians that hated Supply-side Economics needed a real simple strategy to know what to do when Keynesian Economics wasn't working. La Wik says that MMT
describes currency as a public monopoly and unemployment as evidence that a currency monopolist is overly restricting the supply of the financial assets needed to pay taxes and satisfy savings desires.
So, print money until the economy begs for mercy. MMT also says that the government should run "a budget deficit large enough to achieve full employment through a job guarantee." using "non-accelerating inflation buffer employment ratio (NAIBER)" rather than "non-accelerating inflation rate of unemployment (NAIRU)," which I take to be the conventional Keynesian option. In other words, politicians should do what comes naturally without limit.
Stage Eight: Schachtian Economics. Hjalmar Schacht was the guy that ended the hyperinflation in Germany after World War I. He simply stopped printing unlimited paper money.
Here's what I think.
I think that going back to the dawn of time, governments are always cocking-up the economy with their wars or their loot-and-plunder economic policies. And it's worse than it used to be. Back in Stage One it was really hard for the king to loot the place to pay for his wars. Stage Three: Dutch Finance made war-making much easier, but didn't have a real simple theory for dealing with the financial crashes that occurred from time to time, especially after wars when the government attempted to return to the gold standard at the pre-war parity.
Also, I think that as governments have fine-tuned and learned more and more how to use money printing and debt to loot the country that they have had to let the financial system in on the action. So now we have highly leveraged private-equity funds that the government permits, probably because the finance sector is willing to pay powerful people for the privilege of doing highly-leveraged finance.
My guess is that almost all government spending amounts to loot and plunder and is a net loss to the prosperity and the well-being of the people. So, with government spending at 40 percent of GDP in the US and 50 percent of GDP in the UK you can see that there is a lot of looting and plundering going on, and it subtracts from the possible prosperity that might obtain if the government weren't collecting so much of peoples' incomes and handing it out to its supporters.
And, I would say, as government collects and spends more and more money, it needs new theories to justify its looting and plundering and to get it out of a jam when its cock-ups wreck the economy.
The interesting thing to me is that even lickle AOC knows all about MMT. Like in The Manchurian Candidate, your average politician needs it to be "real simple."
But we wouldn't need all these dodges and cunning tricks to pay for wars and entitlements if government would only keep out of wars and away from loot-and-plunder entitlements.
In another world.
