"But we don't do that. And the more I asked why not, and persisted in thinking about the "problem" of schooling as an engineer might, the more I missed the point: What if there is no "problem" with our schools? What if they are the way they are, so expensively flying in the face of common sense and long experience in how children learn things, not because they are doing something wrong but because they are doing something right? Is it possible that George W. Bush accidentally spoke the truth when he said we would "leave no child behind"? Could it be that our schools are designed to make sure not one of them ever really grows up?"
More wonderful insight from John Taylor Gatto- on this particular point it is very interesting to look into the history of the teenager and the elongation of youth.
