Leads to Socialism
Interventionism cannot be considered as an economic system destined to stay. It is a method for the transformation of capitalism into socialism by a series of successive steps. It is as such different from the endeavors of the communists to bring about socialism at one stroke. The difference does not refer to the ultimate end of the political movement; it refers mainly to the tactics to be resorted to for the attainment of an end that both groups are aiming at.
Karl Marx and Fredrich Engels recommended successively each of these two ways for the realization of socialism. In 1848, in the Communist Manifesto, they outlined a plan for the step-by-step transformation of capitalism into socialism. The proletariat should be raised to the position of the ruling class and use its political supremacy "to wrest, by degrees, all capital from the bourgeoisie." This, they declare, "cannot be effected except by means of despotic inroads on the rights of property and on the conditions of bourgeois production; by means of measures, therefore, which appear economically insufficient and untenable, but which in the course of the movement outstrip themselves, necessitate further inroads upon the old social order, and are unavoidable as a means of entirely revolutionizing the mode of production." In this vein they enumerate by way of example ten measures.
In later years Marx and Engels changed their minds. In his main treatise, Das Capital, first published in 1867, Marx saw things in a different way. Socialism is bound to come "with the inexorability of a law of nature." But it cannot appear before capitalism has reached its full maturity. There is but one road to the collapse of capitalism, namely the progressive evolution of capitalism itself. Then only will the great final revolt of the working class give it the finishing stroke and inaugurate the everlasting age of abundance.
From the point of view of this later doctrine Marx and the school of orthodox Marxism reject all policies that pretend to restrain, to regulate and to improve capitalism. Such policies, they declare, are not only futile, but outright harmful. For they rather delay the coming of age of capitalism, its maturity, and thereby also its collapse. They are therefore not progressive, but reactionary. It was this idea that led the German Social Democratic party to vote against Bismarck's social security legislation and to frustrate Bismarck's plan to nationalize the German tobacco industry. From the point of view of the same doctrine, the communists branded the American New Deal as a reactionary plot extremely detrimental to the true interests of the working people.
What we must realize is that the antagonism between the interventionists and the communists is a manifestation of the conflict between the two doctrines of the early Marxism and of the late Marxism. It is the conflict between the Marx of 1848, the author of the Communist Manifesto, and the Marx of 1867, the author of Das Capital. And it is paradoxical indeed that the document in which Marx endorsed the policies of the present-day self-styled anti-communists is called the Communist Manifesto.
There are two methods available for the transformation of capitalism into socialism. One is to expropriate all farms, plants, and shops and to operate them by a bureaucratic apparatus as departments of the government. The whole of society, says Lenin, becomes "one office and one factory, with equal work and equal pay," the whole economy will be organized "like the postal sytem." The second method is the method of the Hindenburg plan, the originally German pattern of the welfare state and of planning. It forces every firm and every individual to comply strictly with the orders issued by the government's central board of production management. Such was the intention of the National Industrial Recovery Act of 1933 which the resistance of business frustrated and the Supreme Court declared unconstitutional. Such is the idea implied in the endeavors to substitute planning for private enterprise.
