It comes down to IQ. (Score 1)

It's as simple as IQ & Numbers. The Chinese and Indians have 10x more than our population. They have 1.2 Billion plus 1 Billion. We have 300 Million. (OK, maybe 9x) Out of our population, maybe only 1% - 10% of our society is intelligent enough to go into engineering. So, 1% of 300 Million is 3 Million. IQ distribution is about the same in any population. So the same goes for Indians and Chinese. So, 1% of 2.2 Billion is 22 Million. We have 3 Million, they have 22 Million. Simple math. Also, since they have so many more to compete, with they are more aggressive at their education.
