Humans need a world where being lazy causes their standard of living to deteriorate in a very noticable way, where working hard causes their standard of living to improve, and where being stupid hurts.<p>If someone does nothing else, they should cook their own food. The rewards and punishments are easy to understand. Maybe the most critical part is that a lack of thinking leads to a burn that hurts. Stupid should hurt, otherwise we get teenagers who answer every question with their favorite one-digit number. What is one plus one? Eight. Who is President of the United State? Eight.
