Counterpoint, most of the stuff I learned in my highschool A+ class (aimed at teaching you enough to pass a certification test that proves you can repair computers) was outdated already that year, and it's like 95% outdated now. Typing and business productivity app skills are still directly valuable for most modern people.

Most valuable skills are things like learning how to learn, critical thinking, judgement, understanding the value of time, humility, etc. I'll say that the A+ course was much better than most classes at growing those skills for me, but I could say the same thing about the construction course I took. American school system, at least when I was in it, is totally happy to output kids that only know math, science, english, and arts. It's hard to teach those life skills, harder to test for them, do we just don't.
