he unity of labor, economic and political, upon the basis of the class struggle, is at this time the supreme need of the working class. The prevailing lack of unity implies lack of class consciousness; that is to say, enlightened self-interest; and this can, must and will be overcome by revolutionary education and organization. Experience, long, painful and dearly bought, has taught some of us that craft division is fatal to class unity. To accomplish its mission the working class must be united. They must act together; they must assert their combined power, and when they do this upon the basis of the class struggle, then and then only will they break the fetters of wage slavery.
