Americans are dying young at alarming rates

We have a pretty substantial "loser class". People that have jobs that don't pay well and aren't held in esteem. Many within this group don't feel they have a chance at upward mobility (and may be right). This has been especially hard on middle-aged people who've seen a tremendous growth in suicidality (which is still less than younger folks, but has seen explosive growth).
We don't treat mental illness and heavily stigmatize it. We engage in a number of habits that likely result in poor mental health. There's less face to face interaction. We spend large amounts of time sitting perfectly still in the same exact spaces, and have poor diets.
There's likely a ton of things that are contributing. I'm not sure there's a silver bullet, singular "cause" that's driving this.
I wonder about the racial differences too. Why are Asian Americans and African Americans much lower? Don't they deal with the same income inequalities?
As the article points out, people are engaging in more self destructive behaviors. These behaviors are much more influenced by social and cultural support systems than anything else.
There are lots of interesting details. Notably, the increases are mostly in the male population.
