Socialism thrives when the alienation of labor survives. This is prevalent throughout the world today, especially in the Third World countries. During the Industrial Revolution, it was present in France and Germany too. This is where Karl Marx formulated his ideas of class warfare, the bourgeoisie, and the proletariat. Marx believed that when the proletariat, the common laborer, felt he created nothing for himself from his labor he would rise up against his employer, the bourgeoisie. Labor becomes alienated when workers surrender control over products and accept wages in its place. Karl Marx’s theory of alienated labor is integral to Upton Sinclair’s story, The Jungle.
