Well, then, if he produces in three or four hours a value equal to the value of his labor-power or wages, why doesn't he stop work then, and take his coat and hat and go home and devote the rest of the day to study, reading, games, recreation and amusement? He don't because he can't. He has to agree (voluntarily, of course) to any conditions that the class who by owning his tools own him choose to impose upon him, and the lash of the competition of the unemployed, Capital's Reserve Army, as Marx called it, is ever ready to fall upon his naked back.
Why is he so helpless? Because he and his class have been robbed of the land and the tools and all the means of sustenance and production, and have nothing left them but that empty bauble, legal liberty, liberty to accept wages so small that they barely enable them to live like beasts, or liberty to starve to death and be buried in unmarked graves by the public authorities.
The wage system necessarily implies this surplus labor or unpaid labor. So long as there are wages, workingmen, you will never get the full product of your labor. Let no reformer beguile you into a struggle which simply aims to secure a modification of the wage system! Nothing short of the annihilation of the wage system will give you justice and give you the full product of your labor.
But while wages necessarily imply surplus-labor, the reverse is not true. You can have surplus-labor without wages. Surplus-labor is not an invention of modern capitalists. Since Mankind emerged from the state of Primitive Communism typified by the Garden of Eden in the Hebraic myth, there have been three great systems of economic organization: 1. Slavery; 2. Serfdom; 3. The Wage System. It is interesting to note the varying appearances of surplus or unpaid labor under these three systems.
Under the first, Slavery, all labor appears as unpaid labor. This is only a false appearance, however. During a part of the day the slave only reproduces the value of his maintenance or "keep." During that part of the day he works for himself just as truly as the modern wage slave works for himself during a part of his day. But the property relation conceals the paid labor.
Under the second system, Serfdom, or the Feudal System,—the paid labor and the unpaid labor are absolutely separate and distinct, so that not even the most gifted orthodox political economist can confuse them.
Under the third system, Wage Slavery, the unpaid labor apparently falls to Zero. There is none. You voluntarily enter into a bargain, agreeing that your day's work is worth so much, and you receive the full price agreed upon. But again this is only a false appearance. As we saw by our analysis, a part of the wage-slave's day is devoted to paid labor and a part to unpaid. Here wages or the money relation conceals the unpaid labor and disguises under the mask of a voluntary bargain the struggle of the working class to diminish or abolish unpaid labor, and the class-conscious, pitiless struggle of the capitalist class to increase the unpaid labor and reduce the paid labor to the minimum, i. e., to or below the level of bare subsistence. In other words the Wage System conceals the Class Struggle.
