Fact #1: American "schooling" (and a lot of other "Western" schooling) is heavily modeled after the Prussian "education" (indoctrination) system.
Fact #2: One of the main proponents of that system (Johann Gottlieb Fichte) openly described the purpose of the system as follows: "Education should aim at destroying free will so that after pupils are thus schooled they will be incapable throughout the rest of their lives of thinking or acting otherwise than as their schoolmasters would have wished."
Fact #3: The book "Obedience to Authority" documents the findings of Dr. Stanley Milgram, and shows that a majority of Americans will inflict severe pain or death on an innocent stranger, simply because a perceived "authority" figure told them to.

That is what American "education" accomplishes. And it does it very well.
(P.S. I could have done my usual routine, and babbled on and on about this subject for many paragraphs, but I think for now, that's about all that needs to be said.)
