You're going to claim that the Google CEO and Microsoft CEO being of Indian ethnicity somehow contributes to India's growth? I think it does the opposite, considering what people of their talent might or might not have achieved if they remained in India.

I'm not saying that they should have remained in India (far from it), but they chose not to so they could contribute to largely American growth.

I do think ambitious & driven Indians can do very well in a global market place. I think the stiff competition in resources have made the cream of India very competitive at a global level and we see things like Indian at Microsoft CEO position. But I dont buy your argument that Indians are outdoing the west yet(not saying it can't be done), but there have been more American CEO's in the fortune 500 than Indian CEOs.
