The best teachers I ever had were the ones that taught the subject material but from a relatable manner based on their years of experience. Yes, the best teachers I personally had were older.
The best teachers I ever had were kind, smart, and well funded.
The second post was that acknowledging the fact that teachers no longer teach but instruct based on a preset curriculum arranged to get grades for specific tests higher.
The fuzzy logic in my head might not be clear to me let alone others, but I feel you're trying to make something out of nothing as well.
Much of the rest is teaching the basics, which, as a functional adult, they should have decades of experience with.
