One seventh of the world's population is Indian born, so perhaps not so surprising...
The fact that middle/lower class Indian-born and educated individuals are now running corporations with the size and impact of Google, Adobe, Nokia, Deutche bank, Pepsi, Microsoft and the likes is just down right stunning. They've broken through cultural, racial, societal, stereotypical, psychological and economical barriers at an extreme level to do so. This needs to be academically investigated.
