I had a teacher like this freshman year for honors english the whole year. He was the first adult to say "question everything I say", and would sprinkle lies into conversation to see if people would question the things he'd tell us. I learned about Ayn Rand and tons of other philosophy for the first time in this class. The only difference was he wasn't any of this hippy bullshit "do you think you're good enough" trash. He was a real ass dude, former veteran, I still talk to him on facebook sometime. All he asked of us was to contribute to discussion
someone else with a similar good teacher:
My history teacher in high school freshman&sophomore years. Always asked questions such as why would this happen or why did that happen. I found out about a year ago that he lost his job because students were complaining that he was asking too much from them.
School is supposed to prepare children for the future, but is in fact a grinder where children go through, eventually coming out tired, weak, apathetic, and often depressed, we're all a victim of such, but often they point out to "successful" children who made it far in life thanks to "education". And it often turns out these people are robots or simple workaholics, but the average child is bound to crack and lose that spark of life, I cracked fairly early on and I lost said spark, but I managed to recover it after I finished high school and spent a couple years on my own reflecting in more important things coming to the conclusion that all that time spent in school could have been used to grow and develop as a human being, physically, emotionally and psychologically, it's terrifying to think that school kept me from experiencing life at its fullest and grow alongside it. So the average male nowadays does not start to fully develop until their early to mid 20s. I often like to pretend I was born while in my 20s, in an attempt to forget my wasted childhood.
Imagine being away from your family, the people are who meant to love and care for you, only to spend your waking hours with surrotavistock mothers who couldnt care less for you and your well-being, pressed into doing menial tasks over, and over, in a hostile environment, and with no outlet for your energy. You can read more about this in the book "The War on Boys" by Christina Summers I know, I know, but pertaining purely to how boys are treated in public schooling, her information is solid. Boys are punished purely for being boys, for being energetic, for being talkative and full of ideas and life. Girls are treated as the gold standard, being quiet and submissive. Imagine being punished for just being yourself, having to carry around a 45lb backpack all day, dealing with bullies, shitty food, demeaning classroom routines, and then taking that home, only to do it tomorrow, and the next day, and the next.
It's horrible, it's maddening. It's disgusting that so much talent, so much wonder and purity is beaten out of our youth. They're turned into soulless automatons and for what? For jobs that are no longer there? For a society that doesn't care for them? I can't imagine a worse fate. I fully agree with OP, don't look for signs to prevent a future bad thing for happening, prevent it from happening to begin with. Such major reform is needed it's staggering.
