Since you mention IIT's may I remind you the only time IIT-JEE papers have leaked has been in Bihar, i think this puts things in a nut shell. We live in a democracy and you have the right to choose your leaders, why is it so difficult to check ones house. Giving me a list of ex PM's who have a 5th generation bihari link will do no good to your house cleaning mechanism. Today Bihar is the cheap labour force, wether it is Mumbai or Bangalore, it is high time this scenario changes, and there are better ways to improve this than to keep blaming the congress.
