Theoretically, then, there exist in the United States all the factors which go to make a class struggle. There are the capitalists and working classes, the interests of which conflict, while the working class is no longer being emasculated to the extent it was in the past by having drawn off from it its best blood and brains. Its more capable members are no longer able to rise out of it and leave the great mass leaderless and helpless. They remain to be its leaders. But the optimistic mouthpieces of the great American people, who are themselves deft theoreticians, are not to be convinced by mere theoretics. So it remains to demonstrate the existence of the class struggle by a marshalling of the facts. When nearly two millions of men, finding themselves knit together by certain interests peculiarly their own, band together in a strong organization for the aggressive pursuit of those interests, it is evident that society has within it a hostile and warring class. But when the interests which this class aggressively pursues conflict sharply and vitally with the interests of another class, class antagonism arises and a class struggle is the inevitable result. One great organization of labor alone has a membership of 1,700,000 in the United States. This is the American Federation of Labor, and outside of it are many other large organizations. All these men are banded together for the frank purpose of bettering their condition, regardless of the harm worked thereby upon all other classes. They are in open antagonism with the capitalist class, while the manifestos of their leaders state that the struggle is one which can never end until the capitalist class is exterminated. Their leaders will largely deny this last statement, but an examination of their utterances, their actions, and the situation will forestall such denial. In the first place, the conflict between labor and capital is over the division of the join product. Capital and labor apply themselves to raw material and make it into a finished product. The difference between the value of the raw material and the value of the finished product is the value they have added to it by their joint effort. This added value is, therefore, their joint product, and it is over the division of this joint product that the struggle between labor and capital takes place. Labor takes its share in wages; capital takes its share in profits. It is patent, if capital took in profits the whole joint product, that labor would perish. And it is equally patent, if labor took in wages the whole joint product, that capital would perish. Yet this last is the very thing labor aspires to do, and that it will never be content with anything less than the whole joint product is evidenced by the words of its leaders.
