“In 1999, the anthropologist Christopher Boehm addressed this issue in Hierarchy in the Forest, which reviewed the lifestyles of dozens of small-scale human groups. Perhaps surprisingly, he found that they are egalitarian. Material inequality is kept to a minimum; goods are distributed to everyone. The old and sick are cared for. There are leaders, but their power is kept in check; and the social structure is flexible and nonhierarchical. It looks less like Stalin’s Russia and more like Occupy Wall Street.”
