I am descended from slaves. So are you. From slave-owners, too. Given
the history of the human race, it could hardly be otherwise.
Slavery was the normal form of social organization from the discovery
of agriculture onwards. It may have been common among hunter-gatherers
long before that, but the evidence is inconclusive. What we do know is
that ownership of human beings is at least as old as civilization. The
cities of Ur and Sumer, of Egypt and Persia, of the Indus Valley and Xia
Dynasty China were built by forced labor.
Slaves raised the Acropolis in Athens and the Pantheon in Rome. They
piled up the ziggurats of Meso-America. Incas, Maoris, Apache: All
accepted slavery as part of the natural order. An Aleutian tribe kept a
special caste of boys raised as girls for the sexual gratification of
its chiefs. An early Indian clan bred slave children for the specific
purpose of sacrificing them. Slavery was so endemic in Africa that it
became more common following the abolition of the Atlantic trade.
This history is what makes arguments about reparations so bizarre.
The people paying up would be statistically certain to have both owners
and owned in their family tree; so would the people accepting
compensation.
