Marx's theory of alienation - Wikipedia

Marx's theory of alienation describes the estrangement of people from aspects of their essential human nature as a consequence of living in a society structured by private property and wage labour. Developed by the German philosopher Karl Marx and first articulated in his Economic and Philosophic Manuscripts of 1844, the theory is a foundational concept of Marxism. At its core, it posits that under the capitalist mode of production, workers are inevitably separated from the products they create, the activity of production, their fellow human beings, and their own creative potential.
