Why Indian and Chinese entrepreneurs are leaving America?

The study, reported in this blog, finds that:

The only advantage respondents typically indicated that the U.S. offered was in the salaries received— 64% of Indian and 43% of Chinese respondents said the salaries had been better in the United States than they were at home.

The other advantage that I see the US still has is the strong institutional framework, relatively low corruption, and the rule of law.
