Honestly, though I sympathise with kids not liking school, I don't really understand why it's seen as so much harder now, to be honest.
I was born in the early 70s. I can't say I liked school much, most of us didn't unless we were greatly academic. I work in the education system now and when I think of how we were treated at school versus now, certainly at primary school, I think it's a damned sight less harsh.
Corporal punishment wasn't outlawed in schools until 1986, my first year of secondary. At primary school, I 'd been smacked so hard by a teacher she'd left a red handprint on my thigh. All I did was make noise in the corridor.
And it wasn't just corporal punishment. Once it was outlawed, teachers still had recourse to the standby sarcasm and humiliation that you simply don't see to anything like the extent you used to.
Nobody gave a shit about your home life or mental health unless you were being beaten at home. These days, as staff, we are constantly on the watch for changes in student behaviour, and way more aware of domestic situations and their impact.
In some ways the rules are more draconian than my 80s schooling, particularly regarding uniforms, but to be fair, I'd take isolation or being sent home over a day of 'witty' sarcasm from the teacher about your wrong socks/shoes/whatever.
Our feelings weren't the least bit relevant or considered. Parents usually backed the teacher, if you got in trouble you rarely told at home because you'd just get in trouble again at home.
I don't know why mental health among children is worse, but I can't help wondering if the fact that most of my peers didn't have expectations, sad though it is, that school was anything other than something you had to do, maybe made us more philosophical about it. We accepted boredom, and poor teaching perhaps more than we should have.
There were songs about it. 'Dark sarcasm in the classroom'. Never a truer line, there. We were just another brick in the wall, but we didn't all fall to bits over it like we were the first generation to not like going to school.
Some of us, a bit older than me, staged protests in the 70s about the violence from teachers, which is partly how corporal punishment became a thing of the past. I think my cohort accepted too much, probably because by secondary school we were just glad we couldn't be hit.
