Communism in China is very different than communism in India. I am sure you don't know otherwise you wouldn't have mentioned about dictatorship!
I guess he is referring to states in south India who are the highest contributors and yet they are the losers. If, I remember there was a video by the late Vinod Dua a few years back where he highlighted what a mess is North India and how much South India is contributing to the development of India more than the North.
I don't have the link as of now but I will try and find it. I saw that video and I still remember there is a big contribution as in tax and other revenue by south Indian states particularly by Kerela and how states like Bihar, UP & MP are granted more revenue by the central government to improve thier revenue.
simply because those states enjoy those rights are the poorest ones I believe, in every country there is a gap between the different regions in all countries and all peoples and therefore they are not only in India and we cannot blame them if they are like this
