It sounds to me like the same kind of thing might also apply in schools.
I'm sure the school teachers and administrators mean well. I'm sure they don't consciously realise what a nightmare their institutions have become for many of the students in their care. Even if they do realise, they didn't choose for it to be that way.
The sad fact is that modern life has become a horrible nightmare for many people, grownups and kids alike. Mindfulness has become a popular attempt to paper over the problems, but in truth, many people who are having coping problems or exhibiting "mental illness" are really having understandable reactions to the dysfunction they're sensing in the world.
To be clear: I'm in no way averse to emotional wellbeing techniques that are effective and that increase the agency of participants. I've gone very deep on this kind of work in my own life, and have benefited greatly.
But I think the outcomes, and indeed the intentions, of mainstream mindfulness programs are quite different to this, and are sadly far more focused on maintaining the status quo for institutions and modern mainstream society.
