Solution: make this country slightly less "dog eat dog" and you'll solve a LOT of social issues almost overnight.
I call this the "loser" class (obviously, I don't personally see them as losers, just in terms of societal expectations). You're supposed to go make money or you're a loser. Hopefully, you're "in charge of people" too, because managers and executives are the only people that contribute to society. Do-ers just cost money. You buy a house and become a homeowner to be a "real American" and not be a loser. You better get a big car and attractive partner too. I think there's a talking heads song about this.
Worse, we think that all failures should be permanent. Once you become a member of this class, especially as you age, it becomes difficult to get out. What have you been doing all these years? Did you not want to sit in a cage for your entire adult life? No degree? Have you ever been fired? Have you had any issues with the law? Well, you're done. No longer a member of the "successful American" class, you're now a loser. A despised and ridiculed lesser class within society.
We'll let a few losers out, and rise to the level of good American, but generally, they stay there. Don't forget that you deserve this, and it's your fault because you're a bad person. I'm not surprised by the suicide rate at all.
That's not necessarily a contradiction, since churches double as social clubs and Christian charity means supporting your neighbour who is in trouble. So if you are active in a church you belong to a circle that is a little less dog-eat-dog. Same thing with immigrant communities.
That would imply that life in the US ~300 years ago, when pretty much everyone belonged to a church, was less dog-eat-dog.
If anything, I would say it was the opposite. People would often shoot someone—someone who is just as likely as themselves to be a "good Christian"—just for being an interloper on their farmland, i.e. for having the opportunity (whether they took it or not) to make off with some of their turnips.
When society says your white privilege means you have no excuse for failure, that is a hard dead end.
