Now the nuances for us in the US specifically: the US system is really good for the most and the least talented. The most talented get access to all kinds of free yet prestigious programs and camps, excellent books in local libraries, and professors in colleges. The least talented are carefully looked after, and they don't necessarily have much pressure to get into a college, and rightly so. It is, unfortunately, the vast middle who get hurt because they squander their time in school. They think they have learned, but they barely scratch the surface. NYT used to report that a straight-A student dreamed to become a scientist, yet couldn't even pass placement test of her college. Malcom mentioned in his book David and Goliath that a straight-A student failed her organic chemistry class in Brown University. Similarly in my personal experience, if it weren't for my teacher, I wouldn't know how deep I could go. If a student like me, who managed to stay top of the classes in elite universities, still needed intense nurturing from my teachers, I'd imagine many more do as well.
