If Harvard MBAs aren't out for the money, who is?

Harvard MBAs are signing a pledge they call the M.B.A. Oath, promising not only to "act with utmost integrity and pursue my work in an ethical manner" but also to "safeguard the interests of . . . the society in which we operate" and "guarding against decisions and behavior that advance my own narrow ambitions but harm the enterprise and the societies it serves." Wharton MBAs are organizing their own ethics clubs and conferences, and making ethics classes some of the most popular at the school (trust me, it wasn't that way in 1999 and 2000, when I attended the school -- did I tell you the story of the kid who made $30,000 one day trading Yahoo! stock during class?).

Columbia MBAs have a new honor code in which students promise, "I will not lie, cheat, steal, or tolerate those who do." A new breed of business school grads promising to be honest, care for society over their own interests, and not put up with book-cooking: What is this, utopia?
