Someday, i hope certain folks will start realizing a few basics about being a student in a b-school: there is a reason for marketing, finance, HR, and other job functions to exist. Understanding and implementing these old and established functions is definitely required for any business or manager to do well. It's surprising when fellow students run down other professions, and put on a strange superiority complex about how their view of the world is the absolute - immature, childish and definitely not leadership material. It's all about synergy between various elements of a business. If one cant even accept them, how will one ever work with them? And one can never be good at all of them... that's why there are other people in the world...with whom one has to work to leverage joint strengths.

On that note - i really cant see any real leaders emerging here... level-headedness, maturity and humility are traits that are required in leaders - and with the arrogance and competitive rivalry of a b-school grad, how many can one find with these essential traits? Is leadership training in b-schools a waste of time, then? Nope. There is a reason for it to exist.

Before you challenge the existence of anything, understand and reflect upon the reason for its existence. You will then be wiser and take the right course of action.
