America has had plenty of its own riots that seem indiscriminate. In 1992 people wondered why rioting blacks destroyed so much of their own property in Los Angeles. For the last several years colleges have been erupting into riots because college administrators try to take away their beer. Let us not forget Woodstock 99 with its fires and destruction. Today teenagers and adults seem willing to kill their own children for the most casual reasons.
Young girls mutilate themselves with razors.
It seems everybody under 25 is pierced or tattooed. I suspect that people are fighting boredom and trying to free themselves for more sensation. I think kids dread something. I think they riot over beer because they don't want the larger society to invade their campus redoubts. To me this looks like the death of imagination, which is just a fancy way of saying boredom.
