Obviously the leap to causation needs to be taken very carefully, but "kids these days" are definitely a bit more sad and suicidal for some reason.
There was always a massive disease burden hidden away in the younger generation, schizophrenic and depressive adults don't just spontaneously emerge. It's just that they wouldn't know about it and their family strongly resisted the notion they have the "crazy" kid, because the stigma was unbearable. Those kids would show up as "slow learners", "attention issues", "troubled", "aggressive", in the penal system, addicts etc. and only much later, if they were lucky, get any kind of treatment for the underlying issue.
Remove the stigma and provide resources and many children will use them, perhaps to the point of over-medicalizing normal human variance.
