The Communist Manifesto
The Communist Manifesto, originally the Manifesto of the Communist Party , is an 1848 political document by German philosophers Karl Marx and Friedrich Engels. Commissioned by the Communist League and originally published in London just as the Revolutions of 1848 began to erupt, the Manifesto was later recognised as one of the world's most influential political documents. It presents an analytical approach to the class struggle and the conflicts of capitalism and the capitalist mode of production, rather than a prediction of communism's potential future forms.

“In proportion therefore, as the repulsiveness of the work increases, the wage decreases.”

Context: The Communists disdain to conceal their views and aims. They openly declare that their ends can be attained only by the forcible overthrow of all existing social conditions. Let the ruling classes tremble at a Communistic revolution. The proletarians have nothing to lose but their chains. They have a world to win.
WORKING MEN OF ALL COUNTRIES, UNITE!
