I have seen this myself. I have also experienced more than a few Indian colleagues who were far more critical of Indians in management than the rest of us were. I feel like there is an extra layer of dynamics that just isn't apparent if you are not accustomed to seeing it.

In a way, the people that despise Indians most are Indians themselves :) I say it in a non violent way, as a self critique and a welcome embrace of ideas outside of the Indian mold.
