Can a whole Culture "jump the shark?" It seems to be a logical question. Just open your eyes and ears and look around. We kind of do live in a TV show. And the decline we are all feeling in every aspect of our lives is palpable.
It all probably happened long ago. Maybe we should wait for future historians to pinpoint the exact point of no return. But there is no doubt that we have made a collective leap over a hungry, finned, predator.
Can a whole culture succumb to ridiculousness? That's easy. Yes, of course!
