The only place where 'India' was mentioned for the link you provided is at the last section towards the end of the page. It just talks about technological advances and how people are related to that, but it doesn't say people are migrating countries because of that.
I really cannot undertand what you are trying to express. I really don't see how 'caste' is linked to the article and your initial comment "80% Indians are willing to migrate to USA...". Please try to understand what the problem is and post comments on how that can be solved, that will make the conversation interesting and live. I am not trying to suppress anything and i see most of the comments here have gone in different directions.
I said in plain English that 80% Indians are willing to migrate to USA or Western Nations at $200/month salary due to lack of http://en.wikipedia.org/wiki/Social_mobility in India.
At the same time lots of Indian's currently staying in US are migrating back to India. There used to huge difference in earning but the gap is now narrowing down.
