The main policy point made in The Bell Curve by Murray and Herrnstein was about how important it is to provide people with a valued place in society. Without purposeful work and meaningful social integration you inevitably get the sort of degeneracy we see spreading. About six pages of The Bell Curve touched on race, so of course that and the ensuing screeching is all anybody remembers. The real social commentary in that book is turning out to be very prescient.
