I’m inclined to believe the theories that American history tends to run in cycles, sociopolitical and economic eras that last for decades before the pendulum swings in a different direction. My hunch and hope is that we’re at the end of the long era that began forty-odd years ago, and that America may now be on the verge of positive change and a bracing cascade of the wildly new and insanely great. But it won’t happen by itself. Pendulums must be pushed.
