Arn't mental illnesses massively over-diagnosed because the availability of approved medications is vast enough to be approved for any diagnosis. This coupled with the general belief that though these medications may or may not cure the the mental unhealth diagnosis they at least cannot cause harm.

So for instance there are 10x + more diagnoses of Schizophrenia in USA than in Western Europe; surely USA can't have a gene pool of Schizophrenics so much larger in a population European Immigrants

A hundred any 25 years ago we rode horses and went to bed when it got dark because we had no electricity, we had oil lanterns, but that's not the point. We have so filled our days to the point we can't cope, total sensory overload. We get to a point where we lash out at everything around us, or focus on one thing and try to totally destroy it. We aren't built to live the way we do and it shows.

And, as shown in a previous posting of mine, mental instability can manifest itself after a person acquires a weapon. The test is supposed to be only during the purchase of a gun. Sort of like issuing a person a drivers license for life.

American propensity for shooting ourselves multifaceted. Other countries seem to have violent video games and their share of mental illness, other risk factors. What to we have that’s different? Too little gun regulation and too many guns.
Psychologically we are all the walking wounded, doesn’t mean we’re not sensitive or sane. We could use some goddam universal health care to treat the mentally ill though.

It's not mental instability. With all the violent movies and video games its actually mental insensitivity. It's just not a big deal anymore to them. They've seen it all their lifes. In my opinion.

Don't remember the last person I met not diagnosed with depression.
