Yes, we have societal problems that contribute to this, but they aren't video games, Hollywood, rap music, etc.
And most shootings are not "mental health" issues, in the sense of someone with a clinical mental health problem. There is a different between that (a clinical issue), and someone who snaps. That's why it makes sense to restrict firearms access for people with demonstrated anger management issues (domestic abusers, for instance).
Is anyone here blaming video games or rap music? Just out of curiosity.
"Clinical mental health problem" is a very convoluted topic, and it's why I didn't use the term. Just because something is not in the DSM doesn't mean there's not research on the phenomenon, or correlating/causal factors with certain behaviors. There are things therapists and clinical psychologists treat which don't fit neatly into a clinical mental health disorder (probably psychiatrists too, ostensibly, but in my experience with our patients at a family practice who were referred to psychiatry, all they do is prescribe pills that don't so much fix a problem as they make you so sleepy you don't care anymore.)
Guns have always been readily available to people in this country. I'm curious as to whether there's data on estimates of guns in the country over time, which could be compared with population over time. In my grandparents generation, I never knew anyone who didn't have at least one. Well over half of the people I know now don't own any. Anecdotal, but it's my working theory. Yet now we have more gun-related tragedies.
SuperMario's point can't be discounted. And I'm not trying to discount your points either. But, for example, the entire copycat paradigm is not what I'd consider a root cause to compete with what I'm saying; it's another symptom downstream of what I'm talking about. Again, I reference the WW2 generation (my grandparents). When tragedy struck, those people didn't see upticks in copycat behavior like we do today. Why?
This ties in to a lot of other areas, I suspect. For example, social media is rewiring our brains in ways we don't even understand, and while the extent and specifics aren't fully understood, what we do know for sure is that it is changing us (the younger the person, the more the change), and it's generally not for the better. None of this has made it into the DSM, and likely won't. But it's real. And the correlations between social media impact on young people and negative behavioral trends for those users is staggering. Does this have anything to do with higher rates of tragic behavior, gun violence amongst them? I doubt anyone can say for sure, but I suspect it does, and the correlation is present, at least.

Pre-post edit: Gallup has info, I just saw, on guns in homes, but it only goes back to 1960 (I'd like to look at something that goes back much further). Households with guns has gone down since 1960, but barely, so let's just call it even. There was a bit of an overall trend down through 2019, which sort of fit my hypothesis, but household gun ownership has ticked back up since 2019. At the very least, it suggests that there aren't
more guns in homes than there used to be. But tragic gun use has definitely spiked nevertheless, so I don't know that gun availability is the best culprit.
