You are 100% right, No American Management School teaches you about society. Learning to be selfish (Sorry.... Being RUTHLESS and GOAL ORIENTED) is the first dictum of Management...Outcome is WORLDCOM...AurtherAnderson and ....nice petrol MNC of US! Management does not teach you to become nice citizen or GOOD HUMAN...(These two things are poles apart). Therefore the behaviour of IIM-A should not be surprising, because an institute trying to emaluate US their idols (US B-Schools) teaches to be selfish. Hats-off mate....I am sure you are CEO material.
