1: That the mental health system is actively harmful or 2: That the mental health field is impotent to address mental health issues

The latter case means that the mental health field could be helping, but at the very least, the mental health system is a distraction from the bigger issue of mental health. I believe declines in mental health are driven by things like increasing inequality, scarcity, competitiveness, loneliness, and so on which we can't nessecarily solve by telling people you are disordered with such and such so live in such and such a way and you can maybe be better adapted to a society which has their collective mental health in freefall.

P.S. I specifically resent the label of "disorder" in general and think that label is part of the problem, because no matter how you spin it, somebody saying you are "disordered" is an insult, and as we call more and more of the population disordered I think the adjective will become untenable to keep using. I'm more keen on the concept of neurotypes, because neurotypes CAN be negative, and CAN require accommodation, and CAN require treatment, but none of those things are NECESSARILY true. If you discover your "neurotype" you can try tools and techniques that helped others with that same neurotype. Whereas the word "disorder" sort of has an intrinsically negative connotation, and I don't think it's medically necessary for psychiatrists to regularly insult their patients.

The mental health system is so fundamentally condescending and some of the shitty things they do don't really get examined or critically looked at that much. Like why don't we ask, is telling millions of people they are "disordered" likely to improve their mental health and confidence and self-esteem? Probably not and it's also probably totally avoidable but I don't think people ask if mental health itself so things carry on.
