http://www.nytimes.com/2004/06/15/opinion/15BROO.html?pagewanted=print&position=It's been said that every society has two aristocracies. The members of the aristocracy of mind produce ideas, and pass along knowledge. The members of the aristocracy of money produce products and manage organizations. In our society these two groups happen to be engaged in a bitter conflict about everything from S.U.V.'s to presidents. You can't understand the current bitter political polarization without appreciating how it is inflamed or even driven by the civil war within the educated class.
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.
Political scientists now find it useful to distinguish between professionals and managers. Professionals, mostly these knowledge workers, tend to vote for Democrats. Over the last four presidential elections professionals have supported the Democratic candidate by an average of 52 percent to 40, according to Ruy Teixeira and John Judis, authors of "The Emerging Democratic Majority."
Managers, who tend to work for corporations, brokerage houses, real estate firms and banks, tend to vote Republican. Thanks to their numbers, George Bush still won the overall college-educated vote.
