The Preamble begins with a classic statement of a two-class analysis of capitalism: "The working class and the employing class have nothing in common." The class struggle will continue until the victory of the working class: "Between these two classes a struggle must go on until the workers of the world organize as a class, take possession of the earth and the machinery of production, and abolish the wage system." The Preamble denounces trade unions as incapable of coping with the power of the employing class. By negotiating contracts, the Preamble states, trade unions mislead workers by giving the impression that workers have interests in common with employers.
