A car flew last night. An actual car, flipping in midair on cold gas thrusters and landing on its wheels. Elon Musk's companies built a sports car that does what science fiction promised for a century. The same man lands rockets on barges and builds the machines that carry our astronauts. That is what one free mind, and the thousands of minds he employs, can produce. Bernie Sanders says billionaires should not exist. He looks at the man who makes cars fly and concludes the problem to solve is that such men keep too much of what they create. He has spent five decades in government producing nothing, yet he claims the moral authority to dispose of the men who produce everything. A man who seeks unearned control over the lives and property of others is corrupt in the fullest meaning of the word, and that corruption runs deeper than any bribe. A flying car is what men do when they are free. A wealth tax is what politicians do to the men who built it. One of them needs the other to survive, and it isn't Musk.
