Consider the absurdity of expecting to raise all students to the athletic ability of those who excel at their respective sports. Then consider that this is the goal of public education regarding academic proficiency. Before we attempted to achieve the same results from children of different capibilities, we had college level, business level and general level. With effort, (or lack therof) you could move from one level to another, but the end result was everyone rose to the highest level of which they were capable, Of course, those on the bottom level were subject to a loss of "self-esteem". So to correct that unspeakable outcome, we attempt to get everyone to the same level, we have created a mediocracy of achievement.
