I don't think it is quite the right comparison. I think most Indians who end up being CEO (or senior executives) in companies have had some sort of post graduate education abroad, or they have work experience starting in a multi national corporation in India.
For excellence in sports, particularly at the olympic level, you need training facilities, budgets and infrastructure in the country. You will find that India is sorely looking in these!
I do not see what the ethnicity of these people has to do with their success. I think more credit should be due to the organisations who hired and supported them up the career ladder.
No, not really true at all. The Sikhs and Malyalees are rather large communities, with large diasporas as well. I think "highhandedness" is too much of a generalisation (?) for such a large and diverse group of people!
You will find that the Sikh and the Malayalis (colloquially, Mallus) were one of the earliest communities to emigrate from India. They've had the time to build a local base in a foriegn country and hence might seem like a difficult group for other Indians to break in to.
The article states that aside from Americans, there are more Indian CEOs than any other nationality - even Canadian and Chinese, which presumably have a higher population in America than Indians do.
Although statistically, Indians should have a few smart people anyways, the number of CEOs the nation exports is disproportionately high in comparison to other countries.
Well, "Few very smart people" does not really correlate to 13 CEOs of the top Fortune companies.
Also, how is population related to this ? Europe also has a population of about 850 million - how many CEOs has Europe produced ? I mention Europe because it's the closest in comparison to India in terms of population diversity.
