I know what you mean, but this documentary was only roughly around what they think it is in reality. This is just a gradual difference that has been noticed since the sixties, is that American academics is starting to fall behind with other competing countries. It really isn't a big deal, considering their facts are only based on the time that American vs Indian vs Chinese students put into classwork. America scored low and that, but because of it, they ranked way above everybody else in self-confidence. So pretty much, in the end, it all balances itself out.
I almost lost myself in those words...
