Apparently the US has the 2nd highest suicide rate out in the Americas according to WHO.
Suicide is usually associated with demonic activity, but there's more to it and the picture can be very complex, in Japan it's also cultural. Weltschmerz however usually afflicts intelligent people.
One aspect I think may play a role, consider Uruguay, a 90% European country which is at 25/100K on that map, the highest of all and above the US. The place is nothing like its neighbors- it's an orderly, high tax country with strong government unions.
Argentina is 95% European but unlike Uruguay the corruption there allows you to circumvent many of the absurdities, relieving the oppressive rat in a cage feeling.
Non-whites have more bad apples.
A lot of usually dumber people don't get depressed when surrounded by slums and general disorder with trash blowing in the air- they adjust comfortably to the surrounding jungle instead of thinking about reining it in and transforming the environment.
Some realize there's no use trying to swim against the current of the broad societal sentiment.
Like Nixon's Ag secretary said- all the colored need to be happy are loose shoes, tight pussy, and a warm place to shit. Littering and stealing doesn't bother them as that's what they like to do themselves, they feel like kings engaging in both and they never feel down.
Rejoice in the Lord and you'll become bulletproof.
