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.
