What is interventionism? Interventionism means that the government does not restrict its activity to the preservation of order, or—as people used to say a hundred years ago—to “the production of security.” Interventionism means that the government wants to do more. It wants to interfere with market phenomena.
If one objects and says the government should not interfere with business, people very often answer: “But the government necessarily always interferes. If there are policemen on the street, the government interferes. It interferes with a robber looting a shop or it prevents a man from stealing a car.” But when dealing with interventionism and defining what is meant by interventionism, we are speaking about government interference with the market. (That the government and the police are expected to protect the citizens, which includes businessmen, and of course their employees, against attacks on the part of domestic or foreign gangsters, is in fact a normal, necessary expectation of any government. Such protection is not an intervention, for the government’s only legitimate function is, precisely, to produce security.)
What we have in mind when we talk about interventionism is the government’s desire to do more than prevent assaults and fraud. Interventionism means that the government not only fails to protect the smooth functioning of the market economy, but that it interferes with the various market phenomena; it interferes with prices, with wage rates, interest rates, and profits.
The government wants to interfere in order to force businessmen to conduct their affairs in a different way than they would have chosen if they had obeyed only the consumers. Thus, all the measures of interventionism by the government are directed toward restricting the supremacy of consumers. The government wants to arrogate to itself the power, or at least a part of the power, which, in the free market economy, is in the hands of the consumers.
Let us consider one example of interventionism, very popular in many countries and tried again and again by many governments, especially in times of inflation. I refer to price control.
Governments usually resort to price control when they have inflated the money supply and people have begun to complain about the resulting rise in prices. There are many famous historical examples of price control methods that failed, but I shall refer to only two of them because, in both these cases, the governments were really very energetic in enforcing or trying to enforce their price controls.
The first famous example is the case of the Roman Emperor Diocletian, very well-known as the last of those Roman emperors who persecuted the Christians. The Roman emperor in the second part of the third century had only one financial method, and this was currency debasement. In those primitive ages, before the invention of the printing press, even inflation was, let us say, primitive. It involved debasement of the coinage, especially the silver. The government mixed more and more copper into the silver until the color of the silver coins was changed and the weight was reduced considerably. The result of this coinage debasement and the associated increase in the quantity of money was an increase in prices, followed by an edict to control prices. And Roman emperors were not very mild when they enforced a law; they did not consider death too mild a punishment for a man who had asked for a higher price. They enforced price control, but they failed to maintain the society. The result was the disintegration of the Roman Empire and the system of the division of labor.
Then, 1500 years later, the same currency debasement took place during the French Revolution. But this time a different method was used. The technology for producing money was considerably improved. It was no longer necessary for the French to resort to debasement of the coinage: they had the printing press. And the printing press was very efficient. Again, the result was an unprecedented rise in prices. But in the French Revolution maximum prices were not enforced by the same method of capital punishment which the Emperor Diocletian had used. There had also been an improvement in the technique of killing citizens. You all remember the famous Doctor J. I. Guillotin (1738–1814), who advocated the use of the guillotine. Despite the guillotine the French also failed with their laws of maximum prices. When Robespierre himself was carted off to the guillotine the people shouted, “There goes the dirty Maximum.”
I wanted to mention this, because people often say: “What is needed in order to make price control effective and efficient is merely more brutality and more energy.” Now certainly, Diocletian was very brutal, and so was the French Revolution. Nevertheless, price control measures in both ages failed entirely.
