It's not his best work by any stretch (its overly dense and repetitive) and some factoids are off the mark, but I do like that he has pointed out that the kind of back-patting altruism everyone likes to pretend is the best reward for their efforts is exposed as the barely upright rationalization for what is otherwise what I call "benign greed". I'm not exempt from it either; I like money, and I like doing interesting things to earn it. If I can make the world a better place for the effort, all the better, but it isn't the raison d'etre, and I won't posture otherwise...a large number of folks in the value do though (possibly to the point of self-denial).
