But really the true culprit is just the youth, and always has been. Ever since the early 1900s traditional family values and social community/cohesion has been seriously on decline. Say what you will about Ted Kaczynski, but his essay/book Industrial Society and its Future is a wealth of knowledge on this subject (strange I know coming from a Christian woman).
But look at it this way: people resort to drugs because reality sucks. Why does reality suck? Well, we live in a society, and this very society (and its implicit social network) causes our youth to suffer.
Just look at how much the new Joker movie resonated with kids, teenagers and young adults! Heck, my niece of 12 years was itching to put on a mask and march in the street after she walked out of the theater. It was terrifying.
