Relax Sugata, it seems you have deeply channelised only into communism. As far as China is concerened the rural life is still deplorable, and the media is not allowed to cover all this, please go see it for your self as I have done so. Besides Beijing, Nanjing and Shanghai, its all down the drains. Moreover China is fast pacing itself towards capitalism, moreover the current prevalent government cannot be described by means of political science as a communist government. I would rather say the it's a one party dictatorship. The biggest collapse of communism can be seen in the fall of the USSR.
India is moving at a fast pace but not enough to be fully developed cause that is going to take a lot of time. The britishers literally whisked away with the resources and kept India in a financial misery. It was somewhat the same in USA too, but they revolted at the currect times. So it is going to take India a lot of time to come to that state. But it is a matter of great pride that India is a nuclear power and it's industries are thriving day by day.
