I say that this interest, all the more then this profit, is impossible.
What are laborers in relation to each other? So many members of a large industrial society, to each of whom is assigned a certain portion of the general production, by the principle of the division of labor and functions. Suppose, first, that this society is composed of but three individuals,—a cattle-raiser, a tanner, and a shoemaker. The social industry, then, is that of shoemaking. If I should ask what ought to be each producer’s share of the social product, the first schoolboy whom I should meet would answer, by a rule of commerce and association, that it should be one-third. But it is not our duty here to balance the rights of laborers conventionally associated: we have to prove that, whether associated or not, our three workers are obliged to act as if they were; that, whether they will or no, they are associated by the force of things, by mathematical necessity.
Three processes are required in the manufacture of shoes,—the rearing of cattle, the preparation of their hides, and the cutting and sewing. If the hide, on leaving the farmer’s stable, is worth one, it is worth two on leaving the tanner’s pit, and three on leaving the shoemaker’s shop. Each laborer has produced a portion of the utility; so that, by adding all these portions together, we get the value of the article. To obtain any quantity whatever of this article, each producer must pay, then, first for his own labor, and second for the labor of the other producers. Thus, to obtain as many shoes as can be made from ten hides, the farmer will give thirty raw hides, and the tanner twenty tanned hides. For, the shoes that are made from ten hides are worth thirty raw hides, in consequence of the extra labor bestowed upon them; just as twenty tanned hides are worth thirty raw hides, on account
