Its a well known fact that the Chinese have the highest average IQ as a nation - 105 ( which is the same as Japs ); the average IQ of Americans is 98 and reducing because of the population of Hispanics and African-Americans increasing fast.
This IQ difference is going to take America back and China forward. ( for the records - current measurements of Indian IQ is 85 - which with better nutrition will rise to 92 by end of century and stagnate then )
