I tend to agree with you there, Jake. Several factors converge, ranging from benefits issues, to excuse-finding for personal shortcomings, to the inherently-unsatisfactory 'Science' of trying to apply a binary 'normal/abnormal' label to an infinitely-varied humanity.
Shit, someone spends some time depressed over real world events that suck and you have people wanting them to hand them happy pills instead of letting them going through the perfectly normal human process of going through something that sucks.
The other thing is if you point out something isn't working or is wrong, we have gotten this mythological idea in our head we can control the environment with our happy thoughts and the very logical negative reaction to something that is negative is something that needs to be cured.
I could go on and on an on.
I openly wonder how many of these mentally ill individuals have been taken advantage of by the "mental health" industry and in fact are just logically reacting to situations in their lives and are being denied the mental thought process to come to solutions for them.
There are people that are mentally ill in our society. There are also people that have found someone who will listen to them about how much their life sucks and instead of letting them find solutions to fix it, enable them to make their lives worse either by prescribing them medications to ignore the reality or by filling their heads with positive thinking nonsense.
My grandparents weren't positive thinkers. I think that is how they survived.
