I feel this is true. I work with lot of B-school guys, they are selfish (there are exceptions), they are money-minded. I strongly believe that one cannot be Leader by attending a B-school. It requies lot of experience. Just learning the Management you cann't be leader. Leader must be visionary and without experience you cann't vision for future. Just reading and studying few book don't mean a leader.
Person must have following qualities
Partnership and voice Vision and values Knowledge and daring Savvy and persistence Personal qualities (passion, humor, and empathy strength of character, general maturity, patience, wisdom, common sense, trustworthiness, reliability, creativity, sensitivity)
