Thomas Sowell wrote:
“In short, the even representation of groups that is taken as a norm is difficult or impossible to find anywhere, while the uneven representation that is regarded as a special deviation to be corrected is pervasive across the most disparate societies. People differ—and have for centuries. It is hard to imagine how they could not differ, given the enormous range of differing historical, cultural, geographic, demographic, and other factors shaping particular skills, habits, and attitudes of different groups. Any ‘temporary’ policy whose duration is defined by the goal of achieving something that has never been achieved before, anywhere in the world, could more fittingly be characterizes as eternal.”
