i don't know where you want to take this critic but there's a lot of learn that is meant to be forgotten. transfer of learning is a scientific phenomenon. how it's useful for the day to day is at least questionable, as it's pretty hard to measure. if you take with a pretty rational look it feels insane to teach kids nobel prize type of knowledge that can't be understood or figured out entirely by crytalized knowledge (which is also a scientific term). how much that's necessary and how some fields like regulating emotions, arts and even critical thinking are missing on the grade, the quote about "we didn't know where to stop" feels pretty prevalent. it's not impossible to find a phd graduate working in some job someone without high-school graduation could learn, probably at the same rate/time span
