I don't truly know if the problem is that people are becoming less socially responsible, or if people are being more desperate. I'd like to believe that people wouldn't choose a life of crime if they'd be able to meet all their needs legally - and so solving problems like the cost of living crisis/housing, etc would see a reduction in these attacks.
In reference to my other comment, I don't think introducing assault weapons into the mix would help here, haha.
Fair point, but what if the hurdle to "being desperate" is lower now due to changes in the ways people manage themselves? I wonder if there were many mass casualty events in the US during the depression in the 30s. There weren't any school shootings like today until in the 60s.
It looks like there were... but obviously dramatically reduced in number. The US probably has this many in a fortnight now... so it's hard to say how much desperation or social responsibility play into this.

I do think the school shootings in the US is from socially maladjusted young men (with likely mental health issues) getting access to assault weapons... whereas the machete attacks in Australia is more likely motivated by gang activity (drugs, money, etc) which are less likely to exist without people feeling desperate.
