Educated people are the way they are due to a particular personality that they have. They are curious and self driven. Many educated people have no formal education. You cannot teach a personality.
That's not to say other personalities are less worthwhile... It's just that we have emphasized one kind of personality as the ultimate one and then are surprised that -- after maxing out opportunities for those already suited towards that personality -- a saturation point is reached and future effort has marginal gains.
