Even in my day schools were beginning to unravel.
Where my high school had once offered Latin, Greek, and Hebrew in addition to several foreign languages things had fallen to just Latin along with German and Spanish.
Students had to opt in to Geometry, much less Trigonometry and pre-Calculus. After gutting it through introductory Algebra most were done except for a follow-up class in Bonehead Math: Relearning times tables, balancing a checkbook, and.. what? Playing records after that first week?
Science? Don't get me started. All optional and taking another Bonehead class would suffice. Many weren't even offered unless you took AP classes and (often) rode another bus to get to the one school in town where those classes were still held. Enrollment was down that far!
History? Again, one General Survey For Dummies class got one off the hook.
I guess they'd fill the rest of their day with Remedial Reading, Basketweaving, Handicapping Horse Races, etc.
But we know why it happened. We went from a culture of opportunity to a culture of outcome-in-name. It was considered too elitist to require earning the privilege of high school and that high school diploma. So mainstream every bump on a log and just hand everybody that cap, gown, and sheepskin. Learning? You were on your own.
Years later I had kids go through the system-as-it-became by the 1990s. Wow, standards had fallen even further. Screens were just starting their creep into classrooms.
Now things have gotten crazy. The trend of subjects coming down from college-level into high school reversed long ago. You can probably "graduate" today without knowing about long division or the oppression of British Colonialism. The Earth is flat became a valid theory. Americans displaced the peoples of the Americas - not the British, French, Spanish, and Portuguese invaders. Bow to authority, don't question, explore, decide for yourself, or be proud to live free.
