The capitalistic mode of production moves in these two forms of the antagonism immanent to it from its very origin. It is never able to get out of that "vicious circle," which Fourier had already discovered. What Fourier could not, indeed, see in his time is, that this circle is gradually narrowing; that the movement becomes more and more a spiral, and must come to an end, like the movement of the planets, by collision with the center. It is the compelling force of anarchy in the production of society at large that more and more completely turns the great majority of men into proletarians; and it is the masses of the proletariat again who will finally put an end to anarchy in production. It is the compelling force of anarchy in social production that turns the limitless perfectibility of machinery under modern industry into a compulsory law by which every individual industrial capitalist must perfect his machinery more and more, under penalty of ruin. But the perfecting of machinery is making human labor superfluous. If the introduction and increase of machinery means the displacement of millions of manual, by a few machine-workers, improvement in machinery means the displacement of more and more of the machine-workers themselves. It means, in the last instance, the production of a number of available wage-workers in excess of the average needs of capital, the formation of a complete industrial reserve army, as I called it in 1845,[6] available at the times when industry is working at high pressure, to be cast out upon the street when the inevitable crash comes, a constant dead weight upon the limbs of the working-class in its struggle for existence with capital, a regulator for the keeping of wages down to the low level that suits the interests of capital. Thus it comes about, to quote Marx, that machinery becomes the most powerful weapon in the war of capital against the working-class; that the instruments of labor constantly tear the means of subsistence out of the hands of the laborer; that the very product of the worker is turned into an instrument for his subjugation. Thus it comes about that the economizing of the instruments of labor becomes at the same time, from the outset, the most reckless waste of labor-power, and robbery based upon the normal conditions under which labor functions; that machinery, "the most powerful instrument for shortening labor-time, becomes the most unfailing means for placing every moment of the laborer's time and that of his family at the disposal of the capitalist for the purpose of expanding the value of his capital" ("Capital," American edition, p. 445). Thus it comes about that over-work of some becomes the preliminary condition for the idleness of others, and that modern industry, which hunts after new consumers over the whole world, forces the consumption of the masses at home down to a starvation minimum, and in doing thus destroys its own home market.
