That doesn't explain the difference between US and the rest. Either the rest of the world has other, more noble purposes, which helps their children to learn better. In this case, should we think about purpose? Or the rest of the world has the same goals and just reaches them better than in US. In this case - should we learn how to pursue them properly? This all is in case US still believes the real education is important. May be it isn't? May be better education doesn't lead to a better life?
