At the German Socialist Congress at Hanover in 1899, Bebel said that even if the income of the working class was increasing, or even if the purchasing power of total wages was becoming greater, the income of the nation as a whole was increasing much more rapidly and that of the capitalist class at a still more rapid rate. The great Socialist statesman laid emphasis on the essential point that capitalists are absorbing continually a greater and a greater proportion of the national income. The class struggle, says Kautsky, rests not upon the fact that the misery of the proletariat is growing greater, but on _its need to annihilate a pressure that it feels more and more keenly_. "The class struggle," he writes, "becomes more bitter the longer it lasts. The more capable of struggle the opponents become in and through the struggle itself, _the more important become the differences in their conditions of life, the more the capitalists raise themselves above the proletariat by the ever growing exploitation_."[209] This feature of present-day (capitalistic) progress, Socialists view as the very essence of social injustice, no matter whether there is a slight and continuous or even a considerable progress of the working class. The question for them is not whether from time to time something more falls to the workingman, but what proportion he gets of the total product. It would never occur to any one to try to tell a business man that he ought not to sell any more goods because his profits were already increasing "fast enough." It is as absurd to tell the workingman that the moderate advance he is making either through slight improvements as to wages and hours, or through political and social reforms, ought to blind him to all the possibilities of modern civilization from which he is still shut off, and which will remain out of his reach for generations, unless his share in the income of society is rapidly increased to the point that he (and other non-capitalist producers) receive the total product. The conflict of class interests is not a mere theory, but a widely recognized reality, and the worst accusation that can be made against Socialists is not that they are trying to create a war of classes where none exists, but that some of them at times interpret the conflict in a narrow or violent sense (I shall discuss the truth or untruth of this criticism in later chapters). Yet Mr. Roosevelt voices the opinion of many when he calls the view that the maximum of progress is to be secured only after a struggle between the classes, the "most mischievous of Socialist theses," says that an appeal to class interest is not "legitimate," and that the Socialists hope "in one shape or another to profit at the expense of the other citizens of the Republic."[210]
