69:8.5
The herders were the first capitalists; their herds represented capital, and they lived on the interest — the natural increase. And they were disinclined to trust this wealth to the keeping of either slaves or women. But later on they took male prisoners and forced them to cultivate the soil. This is the early origin of serfdom — man attached to the land. The Africans could easily be taught to till the soil; hence they became the great slave race.
