As Kennan recognized, however, the maintenance of such a concentration of wealth often requires violent action. Agriculture
is a recent human experiment. For most of human history, we lived by gathering or killing a broad variety of nature's offerings.
Why humans might have traded this approach for the complexities of agriculture is an interesting and long-debated question,
especially because the skeletal evidence clearly indicates that early farmers were more poorly nourished, more disease-ridden
and deformed, than their hunter-gatherer contemporaries. Farming did not improve most lives. The evidence that best points
to the answer, I think, lies in the difference between early agricultural villages and their pre-agricultural counterparts—the
presence not just of grain but of granaries and, more tellingly, of just a few houses significantly larger and more ornate
than all the others attached to those granaries. Agriculture was not so much about food as it was about the accumulation of
wealth. It benefited some humans, and those people have been in charge ever since.
