brain drain

why brain drain in India is very high. If you look at the recent events happening in India you will realise the reason why.
Mr. Narayan Murthy was appointed special IT adviser for Sri lankan president. Murthy was critisized by many political leaders. Naturally he would be fed up of it and now has decided to head the IT department in that country and develop it.
In the need of crisis situation we need someone like him to bring things back to normal, but its very sad to see that he is willing to help other countries before ours. Not his mistake though. When asked about this decision he said that it is his personal matter and wouldnt like to comment on it. He has already set up a big Infosys center in Sri Lanka. He is like a god father of IT industry in that country. So when someone gives a good recognition that he deserves to he would obviously accept it.
