Society has taken a turn for the worse. Rampant Wokeness and PC in schools and corporations and in social media is at the core of this. Not to mention society has moved away from religion also due to PC.
Indeed - society chose to CELEBRATE mental illness. Put it on a pedestal. At least, the homosexual and transsexual forms.
And those’re no longer acknowledged as illness.
As for the other mental/emotional illnesses - it hasn’t been PC for decades to have real “institutions”. So people suffer more - both the ill, and the not ill.
