In Hindi, a "pandit" is someone who has learned and memorized the Rig Vedas and Upanishads well enough that he can be called upon to recite the right sections for weddings, funerals, et cetera.

Hence the modern expression "pundit." Yergin is the best example of a mass media pundit, but if you'll pardon a ribald touch, it seems to me the book he recites from is the Kama Sutra.

I guess the real question then is : who is getting "screwed"
