Try to explain why the rioters are mostly "younger generations"
Some smart person once said that:
"If you are not a liberal when you are young, you have no heart, and if you are not conservative when old, then you have no brain"Young people have an amazing capacity for worrying about things they really have no business worrying about. Old people tend to think only of the problems closest to their own hide. So it has been, since the dawn of our species.
In less words - because young people are stupid.
More specifically, young men are stupid (most of the rioters are male). I know this on my own example. Regardless of all the good knowledge I absorbed from smart people, I was still effectively very stupid when I graduated.
Two huge contributing factors, in young males (again based on my own example), is a sex drive which can cloud all reason (how many of those guys are out there to impress some girl), and a lust for violence (testosterone? Older guys not taking you seriously? Not sure, but it's definitely real).
This is why wars can be good sometimes, because they remove this cohort of rabble rousers, or at least gives them an avenue to vent that stuff.
