I suspect you're probably right, but I'm not sure it's to the point that it discounts their point. I think the "institutional rot" is a smaller factor than other elements impacting mental well-being.
A hormonal, bullied, enraged teenager where I live is less likely to do monstrous amounts of damage to others. They can get easy access to a knife and might own a car. Out of hundreds of people here, I think I know one person who has a gun, and they live on a farm with a rifle that I'd imagine emerges once a year to shoot foxes or kangaroos.
