Most of us live in social worlds that are profoundly unequal, where small elites have vastly more power and wealth than everyone else. Very few of the have-nots find this congenial. As experimental economists have shown, we tend to enter social situations prepared to take a chance and cooperate in collective activities. But if others take more than their share, we resent being played for a sucker. We live in unequal worlds, and few of us are unaware of, or indifferent to, that fact.

Since the elites are massively outnumbered, the origins and stability of unequal divisions of the cake are puzzling, especially once we realise that this is a very recent aspect of our social existence. Our particular species of humans has been around for about 300,000 years and, best as we can tell, for about 290,000 of those years we lived materially poorer but much more equal lives. For most of our life as a species, most communities lived as mobile foragers, shifting camps when local resources became scarce, but probably sticking to a regular pattern over a defined territory.

Mobile foragers live in small bands (tens, not hundreds), but with connections of kith and kin to neighbouring bands, in social worlds of a few hundred to a few thousand. In many respects, these forager cultures are varied. They have differing cultural traditions and face different environments. The Australian Western Desert and the High Arctic could hardly be less alike, and both differ sharply from the rainforests of the Congo basin. Even so, in crucial ways, their social lives are remarkably similar. They sometimes have elders or initiates, but they have no chiefs. No-one has command authority over other adult males. Relations between the sexes vary but, in many forager cultures, women are indispensable, skilled, autonomous and essential props of the foraging economy. They gather plant foods and small game, and make much of the equipment of everyday life. They often have a good deal of social and sexual choice.

In contrast with subsistence farmers, foragers are indulgent towards their children, who roam self-educating in mixed-age groups, learning by exploring and experimenting. While the US cultural anthropologist Marshall Sahlins exaggerated the ease of forager life in his book chapter ‘The Original Affluent Society’ (1972), he was right that they met their subsistence needs efficiently, and often quite quickly, in part through a profound commitment to sharing. These communities didn’t just happen to be fairly equal, but actively sought equality. The Canadian archaeologist Brian Hayden has long insisted that every community contains aggressive, ambitious individuals who’d like to be leaders. Foragers keep these upstarts on a short leash.

Somehow, after 290,000 years of living without anyone having the power to tell us what to do, and with every member of a community having about as much as everyone else, most of us are now subject to command, and with immensely less than a favoured few. Why? [Continue reading…]
