The Berkeley economist rejects Stephen Marche’s argument that Niall Ferguson only says what he says in order to better sell himself to the fatcats who can pay his $75, 000 speaking fee:

Misrepresenting facts and selective editing, DeLong argues, isn’t the best way to promote yourself as a speaker:

It’s a way to get your peers to shift from saying “he is highly entertaining and has a definite point of view that will wake you up” to “he will tell you some things that just aren’t so: you can use your money better on somebody else”.

Contrary to what Stephen Marche says, this kind of misrepresentation is not a good career move on Ferguson’s part-not even with the shortest-run speaking-fee-maximization definition of “career”

But perhaps it’s more subtle than this: Perhaps the process of self-corruption is a long and gradual one, as you increasingly become aware of what the people paying those outrageous fees like to hear, and your thought gradually hews closer and closer to that perspective…until you actually cross the line and go further than your patrons would like. (After all, the Tea Party People aren’t going to shell out 75 grand for NF to come talk.)
