I couldn't disagree more. I went to school in the 70s and 80s and bullying was basically part of the fabric of youth. Everyone had to live with it and the teachers didn't care and in some cases contributed. Now I've brought up kids and I'm the coach of a youth football team and bullying is massively reduced and schools come down on it like a ton of bricks. Being a bully has a stigma now. It used to be practically a badge of honour.
I too was at school in the 70s and 80s and yes I agree physical bullying was bad and teachers often enjoyed making a fool of less able kids. But the difference, particularly with peers, was if you had a scrap with someone, it was generally one on one, now the whole gang culture and normalisation of extreme violence makes it much worse. In addition you also have 24/7 social media where kids can easily change images/information and share things widely to bully kids, often in an anonymous manner and in some cases for the whole world to see.
That said and I think this is the point the other person was making, is the reluctance of schools these days to tell kids that they are not performing at an educational level and instead following a softly softly approach doesn't help them prepare for the world they will enter. Infantilism of kids by parents also doesn't help them develop their emotional response. That continues through to post 16 education and is now even expected in the university setting, which I have seen through my work within higher education.
We have a strange situation where kids (teens) seem to be less psychologically and emotionally mature than they were 30-40 yrs ago at the same age, with many unable to accept failure is part of life and actually key in the process of learning and growing. Meanwhile they are being exposed to some of the most extreme views and images, all pumped via the little box in their hand with algorithms created by the tech giants feeding it.
Bottom line is you cant have the softly softly approach whilst being exposed to the ills of the world and not being equipped to deal with it from a psychological point of view and be able to rationalise it.
In the Adolescence TV series, episode 3 with the psychiatrist, you see the emotional immaturity coupled with the switch to violence as the kid gets frustrated. Now obviously this is an extreme situation, but the propensity of kids to resort to violence when they are challenged by authority seems much higher today than it ever was in the 70s and 80s. I can only remember one instance of a teacher being assaulted by a student when I was at schools, yet talk to most teachers and its a weekly if not daily occurrence.
