Interesting point of view. But as true as the "master race" argument put forth by some others before.
Some states have done more for their people than others. Within the parameters of a corrupt environment, some states have provided a better business environment instead of giving free milk or having loan melas.
The southern states and Gujarat and Maharashtra have been luckier in that respect than say West Bengal. To say that the prosperity in the south is because Madrasis (purely as an example) are "more Indian" or "more hindu" or "more tamil" or whatever than Bengalis (purely as an example) is an argument that is very weak on data.
