You're wrong. Watch the two documentaries called 'High School' and 'High School 2'. The way schools are structured absolutely do kill, in almost all cases, any persons desire to learn, along with their general spirit and enjoyment of living. One of the documentaries, I honestly forget which, is of a school that decided to try instead centering every single class on critical thinking. Instead of teaching by fiat, the teachers gave the students the tools to question them and encountered them as intellectual equals, two thinking human beings one of whom simply had more knowledge in an arena than another. When they didn't know the answer to a question, they'd admit it and try to figure it out with the student. It took a poor Latino neighborhood school and created the class that set the record for number of students to go on to receive a college degree - across any school in the country.

But it's hard to teach if you have to treat the students like people, and teachers for the most part go into it because they were very good at manipulating the arbitrary meaningless systems of rules at schools when growing up, then got scared by the whole 'you have to have reasons' part of reality so fled back into the school system as teachers where no reason was needed. No hats indoors? Sure! It's law! No shorts? Or maybe mandatory shorts? Whatever, nothing matters, they're just kids you can restrict and regulate them all you want to make your own life easier, no one will stand up for them!
