“Slavery may change its form or its name -- its essence remains the same. Its essence may be expressed in these words: to be a slave is to be forced to work for someone else, just as to be a master is to live on someone else's work. In antiquity, just as in Asia and in Africa today, as well as even in a part of America, slaves were, in all honesty, called slaves. In the Middle Ages, they took the name of serfs: nowadays they are called wage earners. The position of this latter group has a great deal more dignity attached to it, and it is less hard than that of slaves, but they are nonetheless forced, by hunger as well as by political and social institutions, to maintain other people in complete or relative idleness, through their own exceedingly hard labor. Consequently they are slaves. And in general, no state, ancient or modern, has ever managed or will ever manage to get along without the forced labor of the masses, either wage earners or slaves, as a principal and absolutely necessary foundation for the leisure, the liberty, and the civilization of the political class: the citizens. On this point, not even the United States of North America can as yet be an exception.”
