I take it that you are a teacher, or support teachers and their union. A student can only go so far and be only so successful, in general, depending on their teacher, that the students are all failing, it’s not a reflection on the students, individually, may be on their families, but absolutely it is a reflection upon the teachers in the schools.
No, I'm a retired hardware/software engineer that can credit absolutely none of my education to schools. I have a BS in Computer Science; however, most of what I learned in school came from the IBM CE (Campus IBM 360 and 1130) and my own self study.
Anyone who thinks teachers factor into the learning process in a significant manner are doomed to learn very little. I have a lot of books covering a lot of subjects. Nobody made me buy them or read them.
