Well, given that most people in the world by far live outside the U.S.A, and that people that do not have opportunities are outside the US, in my opinion the low hanging fruit for innovation is in Africa, South America and China,and India not the USA. In Africa you have kids that are not well fed and after 2 hours of intellectual work they can't continue because of the low nutrition of food!! In equatorial Africa I can't even think clearly myself because of the intense heat all year long. In India and South Asia it is worse half a year because of humidity. I seriously believe that climate has a lot to do with intellectual output, specially math is very sensitive to outside temperature. China probably has the brightest near future, but for this it has to change their culture. Innovating is breaking and changing the rules, something China is very bad at.
