A City Guide To Yuci for Marx opens the Communist Manifesto, which he co-wrote with Friedrich ENGELS, with the warning that the specter of communism is haunting Europe. In this work, Marx describes all history as the history of class struggle: the battle between the bourgeoisie (capitalists) and the proletariat (workers). Because of the greed of the capitalists, the worker is always exploited and victimized. The goal of socialism, Marx insisted, was not to abolish private property but to abolish the mistreatment of workers that resulted from unchecked capitalism. He argued that at least nine-tenths of the population owned no property. Marx’s labor theory of value states that the value of a product is derived from the labor involved in producing it. He maintained that the worker earns the subsistence wage in the first six hours of the working day. A City Guide To Yuci 2016.
