i definitely agree with this
Parents need to do their part, too. People thinking that schools alone are responsible for these things are just wrong. People blame teachers for their kids' problems when they're sending a little demon to school. >

I didn't think this was an unpopular opinion, until I saw people disagreeing in the comments.
Society is so dynamic nowadays, it's changing faster and faster, and the current western school system is woefully inadequate.
During the industrial revolution, schools were standardised, and their purpose was to prepare young boys for jobs in factories and prepare young girls for homemaking. Nowadays it seems like their singular function is to prepare students to move on to college or university and that's it.
Unfortunately with higher education becoming so saturated, university degrees are becoming less and less valuable. Especially if you get something like communication, or gender studies.
I think the purpose of school should be to prepare children for life. Many people will say "that's the parents job", and it is  as well. But sadly, many children aren't lucky enough to have competent or caring parents. So I think teaching kids about mental health, and good mental hygiene practices can only be beneficial.
Especially in the environment of today. Teenagers are especially susceptible to negative self perception and depression, and this is magnified by social media and atomisation. The world we live in now has become a lot more detrimental to our mental health than it was 50 years ago. I struggle as an adult sometimes - it's even harder for teenagers that haven't built their whole identity yet.
By preparing children for the real world, by teaching them about mental health, teaching them how to handle money, apply for jobs,, take care of a house, raise kids if they want them, they would be far more equipped to deal with life. And in the long term, they'd likely put less strain on the healthcare system, have less debt and be better parents. Win, win, win!
