Sounds like you are afraid of their talent. Just like Trump:
But seriously, India is a country of 1.5 billion. The US gives out 85,000 H1B visas per year. It's mind-boggling to me that such a tiny visa program has become a huge domestic issue in India. Even Rahul Gandhi brought it up in recent days as a knock on Modi. The Indian media is full of stories on the topic.
It says a lot about the mentality of the Indian upper-middle class and their desperation to leave India. Was it ever this bad for China? I can't recall that it was.
Pretty bearish sign for India, IMO.
