Mars, i agree with the basics of your point. Let me draw a similar comparison with private vs public education. I doesn't really matter if you have a either to succeed in life, but let's be fair, the contacts, network that you develop in private school are invaluable besides the (supposed) higher quality of eduction. It is much the same with MBA - you get a group of highly ambitous, career driven people together in one environment...the network power that this develops is priceless, rather than the actual education you receive.
