I've said it before:
Just give everyone a gun. A real, working gun. And I do mean everyone.
The thing about all our moral and orderly societies is that they all sprang from barbarianism. Mankind at first was just a bunch of stupid murder monkeys who went around saying "unga bunga" and clubbing each other.
And the funny thing is this "throw them into the deep end of the pool and they either sink or swim" method... worked. All peoples, independently, realized that being a murder-hobo monkey was not good and adopted some sort of self-regulation. Now granted, this has its issues (the first kings were just murderhobos who convinced everyone else to either give them food or else convinced other people to murderhobo on their behalf, hence the whole foundation of government is based on an evil premise)....
..... And yet, society existed and even flourished.
Our modern woes are basically down to the fact that mankind stopped being challenged by outside forces (including other human tribes). When people have nothing to rail against, they become their own worst enemy, and hence, start to degenerate as we've been seeing.
The answer, then: reintroduce an element of barbarianism into modern society by giving literally everyone (even the degenerates) an easy way to kill people. Possibly even go a bit further and make murder legal for ten years, as long as its done with the government-issued gun.
I guarantee you that a decade later, all this autism will be over and we will be back on track.
(first person to compare this to The Purge gets a punch in the gut).
