Teaching contemporary inequality can be significantly enriched by being nested in its dynamics over the course of human history. This essay is intended to provide those teaching inequality with a brief sketch of: a) the original human condition of a high degree of equality that endured for 97 to 98 percent of our species’ existence as foragers and early agriculturalists; b) the origin of extreme inequality that accompanied the rise of states and civilization about 5,500 years ago as weapons technology enabled a few to subjugate the producers; and c) why, despite political democracy, extreme inequality persists.
