Capitalist Civilization has endowed the wage-worker with the metaphysical Rights of Man, but this is only to rivet him more closely and more firmly to his economic duty.
“I make you free,” so speak the Rights of Man to the laborer, “free to earn a wretched living and turn your employer into a millionaire; free to sell him your liberty for a mouthful of bread. He will imprison you ten hours or twelve hours in his workshops; he will not let you go till you are wearied to the marrow of your bones, till you have just enough strength left to gulp down your soup and sink into a heavy sleep. You have but one of your rights that you may not sell, and that is the right to pay taxes.”

Paul Lafargue
"The Rights of the Horse and the Rights of Man" (1900)
