A friend tells me that American history travels in arcs, like a pendulum swinging back and forth. Many share this perspective.
Right now, I think of American history as a roller coaster. If you are a fan of roller coasters, you love those sharp turns and steep drops—the sharper and steeper the better. It is artificially death-defying because you are sure you will not die, or even be hurt. You have confidence that all those who brought you to that moment on the ride—the designers, manufacturers, maintainers and operators—have taken scrupulous care to make sure that at that moment and at every moment, the roller coaster is safe. Nothing less will do.
Trump is designing, manufacturing, maintaining and operating the current American roller coaster. How safe do you feel?
