Dan Drezner on Ferguson and Zakaria:
Intellectual power and responsibility in an age of superstars
I don't think it's fair to suggest that Ferguson's critics are jealous of his income.
Now, of course, he's not stupid -- the market for telling rich and powerful people what they want to hear is very large indeed and he's clawing his way to the top of it -- but he's not much of an intellectual either. Perhaps I'm just a silly old romantic but 'intellectual' suggests to me someone who venerates ideas and truth-saying above stroking their own ego, lining their own pockets and sating the appetites of the powerful.
Intellectuals say what they believe, regardless of who is listening and/or paying. Someone who does the contrary is just a big-talking pseudo-celeb.
