看来您老兄是没进过门儿的，道听途说了一connection

Wharton claims the largest alumni pool, but wave is completely useless either. You classmates or teammate? Forget it. The first thing you learn in business school is how to maximize your own return. If you have nothing to trade with them, they will never help you. It is common both in China and America. So, the helps come when you are successful and will never need them.
