"The Proletariat in Marxist theory

In Marxist theory, the proletariat is that class of society which does not have ownership of the means of production. Therefore, the only source of income for proletarians is wage labor.

Marxism sees the proletariat and Bourgeoisie (owner class) as inherently hostile, since (for example) factory workers automatically wish wages to be as high as possible, while owners wish for wages (costs) to be as low as possible."

the personal computer has a lot to do with the means of production of information. storage and transmission too. to quote the journalist A.J. Liebling (1904-1963), 'Freedom of the press belongs to those who own one.'

according to this document on communism, the proletariat was entirely the result of automation by machines. The creation of mass-production and the elimination of cottage industries. the solution, according to the document, is the elimination of private ownership.
