"What's the single most important thing to learn from an economics course today? Â What I tried to leave my students with is the view that the invisible hand is more powerful than the [un]hidden hand. Â Things will happen in well-organized efforts without direction, controls, plans. Â That's the consensus among economists. Â That's the Hayek legacy."
