Marx's theory of human nature in the context of "Marx's theory of alienation"

Karl Marx's theory of alienation describes the separation and estrangement of people from their work, their wider world, their human nature, and their selves. Alienation is a consequence of the division of labour in a capitalist society, wherein a human being's life is lived as a mechanistic part of a social class.

The theoretical basis of alienation is that a worker invariably loses the ability to determine life and destiny when deprived of the right to think of themselves as the director of their own actions; to determine the character of these actions; to define relationships with other people; and to own those items of value from goods and services, produced by their own labour. Although the worker is an autonomous, self-realised human being, as an economic entity this worker is directed to goals and diverted to activities that are dictated by the bourgeoisie—who own the means of production—in order to extract from the worker the maximum amount of surplus value in the course of business competition among industrialists.
