Karl Marx

"The directing motive, the end and aim of capitalist production, is to extract the greatest possible amount of surplus value, and consequently to exploit labor-power to the greatest possible extent."

"As the chosen people bore in their features the sign manual of Jehovah , so the division of labour brands the manufacturing workman as the property of capital ."

"Capitalist production, therefore, develops technology, and the combining together of various processes into a social whole, only by sapping the original sources of all wealth — the soil and the labourer."

"Of all the classes that stand face to face with the bourgeoisie today, the proletariat alone is a really revolutionary class. Paragraph 44, lines 1-2."

"The immediate aim of the Communists is the same as that of all the other proletarian parties: Formation of the proletariat into a class, overthrow of the bourgeois supremacy, conquest of political power by the proletariat. Paragraph 7."
