An evil of civilization
Slavery enters human history with civilization. Hunter-gatherers and primitive farmers have no use for a slave. They collect or grow just enough food for themselves. One more pair of hands is one more mouth. There is no economic advantage in owning another human being.
Once people gather in towns and cities, a surplus of food created in the countryside (often now on large estates) makes possible a wide range of crafts in the town.
