"The obvious differences apart, Karl Marx was no more a reliable prophet than was the Reverend Jim Jones. Karl Marx was a genius, an uncannily resourceful manipulator of world history who shoved everything he knew, thought, and devised into a Ouija board from whose movements he decocted universal laws. He had his following, during the late phases of the Industrial Revolution. But he was discredited by historical experience longer ago than the Wizard of Oz: and still, great grown people sit around, declare themselves to be Marxists, and make excuses for Gulag and Afghanistan."
