Just as you can't teach integrity or morals.
But MBA schools and colleges sure can charge a lot of money to a lot of naive people making them think such things can be "taught."
Which behooves a question (that I ask in my book):
"How, precisely, does a 22 year old fresh out of "business school" think he's smart, able or experienced enough to lead anything?"
I know, I know. Why ask the question.
