A Fairy Tale for Children
I'm not sure exactly when the "Violent Unknown Event" took place, but by the end of the Seventies it had done it's work and there were no adults left. Of course there were individuals that still professed to be adults but they were mocked like Joe Friday talking to a hippy. No one in any kind of authority could be seen as having altruistic motives, in fact the very reason they had authority meant they were greedy and corrupt.
Today we just have children of various sizes, some have drivers licenses and some don't.
