How do you suggest we reduce the prevalence of guns / improve gun control in the US? Keep in mind that the US is not a functioning democracy and its political system is structured to allow any side to block any substantial reform.

Are you answering your own question? I read your reply as :

"How do we stop Z? X and Y are the cause of Z.

The thing is, I said gun control, but I'm not even sure that's real issue. I kinda took it backward. There are mass shootings because of the ease of access to guns, but it's not the ease of access to guns that pushes people to this.

In other ords, remove the guns, the mechanisms that drive people to think they want to kill remains. I might be wrong but it feels like in Europe there are more and more cold weapons attacks, or the use of ramming trucks.

I guess I have no suggestions.

Gun control can’t be implemented in the US because the political system makes it impossible to do so. I don’t know any way to change this.

As for the problems that would persist even if we could ban guns: I don’t know how to fix those, either.

The political system in the US is unique among developed countries. What, concretely, do you suggest should be done?
