> That doesn't really make sense, does it? These issues have been going on for centuries; how does that explain a rising trend?
I think basically this is just a visibility issue: the problems always existed, we just used to accept them as inevitable. We just demand more of life today, and actually pay attention, and that's a good thing.
There was a notion in the past that suffering was normal, and unusual behavior that very distressed people exhibit was just people being people. Like if you survived hunger in the great depression and a few decades later during boom times you still hid money in the seat cushion and wore rags and and went into fits when someone suggested you ought to spend the money you saved a bit more for your own good, no one thought that that was a form of suffering a doctor should help with. Not for poor people anyway. Or if you had been assaulted a woman who was assaulted by their husband and couldn't tell anyone about it, or if you were harmed by the clergy, or if you're a veteran who has a breakdown every time a loud noise happens, and all these other scenarios. Any unusual response to all that wasn't seen as a medical problem to be named and treated at a mass scale, I personally think because learning more about these things medically and making societal adjustments to prevent these things from happening required that society face some extremely uncomfortable truths, which did not happen easily or on its own.
And in fact I feel like the opposite even happened: I read, for example, about how shell shock was purposely not considered a real medical issue in WWI in the UK, to be able to return soldiers to the front as fast as possible even though more than a quarter of soldiers in the hospital were considered shell shocked. Eventually, the diagnosis was banned by the brits. Official shell shock rate at 0%. If you don't look, there's no problem, right?
So instead it was said that there's nothing wrong with you, you just need some rest. And if you had a really severe case and were not better, you were just weak or a coward, and you need to man up and get back out there. Then you get a court martial or electric shocks. It's no wonder that people pretended that they had nothing wrong with them - nothing good happened otherwise anyway. And so no wonder it took so long for society at large to accept this as a problem.
So now we finally have a more accurate pulse on these types of problems, and we see that unsurprisingly they rise as people have problems in their lives. Makes perfect sense to me.
> I'd rather assume that the lack of a framework to understand the harshness of the world is what makes people go crazy.
The framework is realism: it is very much that people do understand that the world is harsh and that hurts you, but then you now get to recognize that it hurt you and do something about it maybe.
