MBA; Mighty Big Abscess

You know the FedEx commercial where the woman says “Oh you’re an MBA” at which time we all decide the guy she’s talking to is an idiot and know not to trust him with anything more than 3 marbles and a deck of cards or someone could get hurt.

I ask this; does anyone know why the MBA programs were developed other than to suck money out of unsuspecting yuppies and show them how to produce more paper than Charmin, Scotties and Cottonel combined in an afternoon? For the follow up bonus question can anyone think of a benefit to the good of human kind?
