" Professionalism is “postindustrial ideology,” and today the Democrats are the party of the professional class. The party has other constituencies, to be sure—minorities, women, and the young, for example, the other pieces of the “coalition of the ascendant”—but professionals are the ones whose technocratic outlook tends to prevail. It is their tastes that are celebrated by liberal newspapers and it is their particular way of regarding the world that is taken for granted by liberals as being objectively true. Professionals dominate liberalism and the Democratic Party in the same way that Ivy Leaguers dominate the Obama cabinet. In fact, it is not going too far to say that the views of the modern-day Democratic Party reflect, in virtually every detail, the ideological idiosyncrasies of the professional-managerial class.
Liberalism itself has changed to accommodate its new constituents’ technocratic views. Today, liberalism is the philosophy not of the sons of toil but of the “knowledge economy” and, specifically, of the knowledge economy’s winners "
