Bobo Brooks sez:

The percentage of voters with college degrees has doubled in the past 30 years. As the educated class has grown, it has segmented. The economy has produced a large class of affluent knowledge workers -- teachers, lawyers, architects, academics, journalists, therapists, decorators and so on -- who live and vote differently than their equally well-educated but more business-oriented peers.

Teachers and decorators are "affluent" enough to be comparable to lawyers and therapists -- as well as the "business-oriented" "managers" on the other side of Brooks's divide. Who knew?
