What Sekhar says about groupism is 100% true. They acheive everything through groups (like a mafia!). During my stay as a PhD stduent in one of the world's leading unverisities, I never saw one moving on his own. As my friend sekhar says, this groupism is followed by people of other religions also. Only those OBC and some FC Hindus don't know this and remain naive and become under achievers for no mistake of them. But in India it is these guys that never enjoyed any benefit, poor guys!
