Well, mass shootings are increasing as well

That would seem to qualify as "boiling over" to a certain extent to me

That is a US centric issue. There are a lot of "unhappy men" in the rest of the western societies as well, and no atrocities like that. Thankfully.

Mass stabbings then

That sounds more covering the issue rather than addressing the root cause.

I've never heard of a treatment where the symptoms aren't treated while the root cause is sought and hopefully tackled.
