I have a slightly different view of this. Here are the key reason why Indian's are succeeding:

1. Speaking the facts does not exist in India. Everyone sugarcoats. The successful see-through sugar coating. They are able to see through the true intentions of their peers, allowing them to be better leaders.

2. Indian's do Jugaad from birth. It is a need, as many don't even have stable electricity to light up a study lamp. They find creative ways to live their lives. This Jugaad at an early age gives them the "Power of Unlimited Thinking". A critical component in being a visionary leader. Finding solutions where no one thought it was possible.

From the article, "Indian-origin people account for just about 1% of the US population and 6% of Silicon Valley's workforce ..."

Really? In tech organizations (in SV), and we are talking about tech companies here, I feel Indians make up about 40% of the workforce. They are so dominant statistically that I have to always remind myself not to be racist when faced with organizational dysfunction caused by "management".
