Another great post Abi! I have two thoughts:

1. Regarding social issues affecting mental health. Let's not forget about culture-bound syndromes (ex. amok, koro, latah, or piblokto). Western societies have their problems (the exact you mentioned) but other cultures, even primitive tribes, have a similar degree of mental problems (not mentioning other health/poverty problems).

That does not mean that we shouldn't do anything about that, of course! Doing research, educating and designing our society in a way that benefits our mental health is something beautiful. So I'm happy that positive psychology is getting recognized (and it's a wonderful antidote to awful poor quality coaching).

By the way, there is also a rather radical claim made by James Hillman that psychopathology (or psychopathologizing as he would say) is one of the core of human Soul, and that's innate to the psyche. And without it we wouldn't be humans.

1. As far as I remember from research, best results from depression treatment are achieved with medication-assisted therapy. However, there is some research on using psilocybin in treating depression (and other disorders) and some studies suggest that it beats both classical ssri's and traditional therapy. I do not advocate for using it on your own, but controlled by a specialist therapy may revolutionize psychiatry and depression treatment (and that is the thing that pharmacy may be afraid of, since one single high dose of psilocybin taken in presence of a therapist seems to be very effective and the decrease seems lasting many weeks or even months - so people may not have to take one ssri everyday and that means less money spend on meds).
