'that a generation of Indians has benefited from upbringings in a culture that, at its best, values humility, close-knit family ties and respect for all walks of life.'

Lol, how does that match with India's caste system? So much respect for lower castes, a huge gap between poor and rich...so much humility...

Probably a corporate environment very much matches a caste system, hence Indians are the most suitable for running such an environment.

And lets not forget, the author is Indian.
