You hit a lot of the points that John Taylor Gatto wrote about in The Underground History of American Education. Think its online free to read now.
Anyways, the Prussian school system is designed to destroy “thinking outside the box” by using peer pressure and humiliation to form “group think”—the one way to think about any issue-—the Marxist, collective, no God way.

You never were forced to attend school—just went if you wanted to learn—so if the kids didn’t like the teacher—if the teacher never taught them anything—they never even attended school.
Our most free thinkers and most intellectual ones-—people who don’t conform to public pressure were most likely home-schooled or taught by a tudor like Lincoln and our Founding Fathers. People who never ever were afraid to express their opinions—because they were not conditioned for 12 years to feel humiliated for thinking differently from peers and corrected by a “teacher” to “guide” them to the “correct” relativistic worldview.
All children in public schools prior to Dewey were taught Objective Truth and learned passages from the Bible and strict discipline was always important to the classroom. Not since the Marxists took charge though—now every thing is set up for brainwashing into moral relativism—to destroy the principles of our Constitution-—Natural Rights from God. Kill God—they kill all morality and society collapses. Nietzsche, and even Freud knew that.
