The wages of hate

Steven Levitt blogs about his latest academic paper, Hatred and Profits, co-written with Roland Fryer. Levitt and Fryer argue that despite the size of the Klu Klux Klan in the 1920s and the education levels of its members, the group had little measurable impact on US society or politics. "It was, however, an incredible engine for generating profits for Klan leaders."

The paper would seem to support a general point we may be familiar with in general terms, but don't often see detailed evidence for, about entrepreneurs of hate in many times and places.
