The objections which the various schools of Sozialpolitik raise against the market economy are based on very bad economics. They repeat again and again all the errors that the economists long ago exploded. They blame the market economy for the consequences of the very anticapitalistic policies which they themselves advocate as necessary and beneficial reforms. They fix on the market economy the responsibility for the inevitable failure and frustration of interventionism.

We may depict conditions of a society of agriculturists in which every member tills a piece of land large enough to provide himself and his family with the indispensable necessities of life. We may include in such a picture the existence of a few specialists, artisans like smiths and professional men like doctors. We may even go further and assume that some men do not own a farm, but work as laborers on other people’s farms. The employer remunerates them for their help and takes care of them when sickness or old age disables them.

The inequality of incomes and wealth is an inherent feature of the market economy. Its elimination would entirely destroy the market economy.2

The market economy involves peaceful cooperation. It bursts asunder when the citizens turn into warriors and, instead of exchanging commodities and services, fight one another.

The market economy, say the socialists and the interventionists, is at best a system that may be tolerated in peacetime. But when war comes, such indulgence is impermissible. It would jeopardize the vital interests of the nation for the sole benefit of the selfish concerns of capitalists and entrepreneurs. War, and in any case modern total war, peremptorily requires government control of business.

If an economically self-sufficient man starts a feud against another autarkic man, no specific problems of “war-economy” arise. But if the tailor goes to war against the baker, he must henceforth produce his bread for himself. If he neglects to do this, he will be in distress sooner than his adversary, the baker. For the baker can wait longer for a new suit than the tailor can for fresh bread. The economic problem of making war is therefore different for the baker and for the tailor.

What distinguishes man from animals is the insight into the advantages that can be derived from cooperation under the division of labor. Man curbs his innate instinct of aggression in order to cooperate with other human beings. The more he wants to improve his material well-being, the more he must expand the system of the division of labor. Concomitantly he must more and more restrict the sphere in which he resorts to military action. The emergence of the international division of labor requires the total abolition of war.

All action involves the employment of scarce means to attain the most valued ends. Man has the choice of using the scarce means for various alternative ends, and the ends that he chooses are the ones he values most highly. The less urgent wants are those that remain unsatisfied. Actors can be interpreted as ranking their ends along a scale of values, or scale of preferences. These scales differ for each person, both in their content and in their orders of preference. Furthermore, they differ for the same individual at different times.

It is evident that things are valued as means in accordance with their ability to attain ends valued as more or less urgent. Each physical unit of a means (direct or indirect) that enters into human action is valued separately. Thus, the actor is interested in evaluating only those units of means that enter, or that he considers will enter, into his concrete action. Actors choose between, and evaluate, not “coal” or “butter” in general, but specific units of coal or butter.
