I agree that was a pretty low point, but I think it started long before that. However, that really is a rabbit trail. I blame The Enlightenment, which prioritized the individual over larger orders like nature, culture, civilization, common sense (!), and spiritual understanding.
We used to have to read The Great Gatsby in English class, and that described another really devastating time.
We used to say the pledge of allegiance in school and we used to have a morning prayer in school and that was a secular school. We used to read real history books about George Washington and such. I was born in 1943 and things have sure changed since then that is for sure. If we misbehaved in school we got a paddling from the principal and then when we got home we got another paddling from out dads. Maybe we should go back to those days and throw that Dr. Spook book out the window.
