The US had the best educational system in the world. Some of the greatest achievements were by products of the 60's educational system (moon landing).
Teachers didn't take ANY crap from students, parents, or politicians. Nobody citizen groups were telling teachers to teach creationism in science class. Teacher unions were strong and teachers were respected and feared.
Now young teachers bow down to parents, kids, and any active parent group. Certain parents suck the life out of educators with all their egocentric demands. Too bad.
