Or another thought: Capitalism.
A businessman is on holidays on a tropic island. He is walking along the beach and sees a local lying on the beach. "What are you doing local man" he asks. "I am lying on the beach". "Yeah I can see that, but shouldn't you be working?" "I did my work already this morning. I am a fisherman and I caught enough fish to eat". "Well, that's not very clever of you. You should go out and fish again to catch more fish, more than you can eat". "That would be stupid" the man answered. "No, not at all, you can sell the fish, so you can earn money". "Why, what should I do with money?" "Money you can save. And when you have enough money you can buy another boat and let fish other locals for you, so you can earn more money and buy more boats and so on". The local looked puzzled to the businessman. "What is the meaning of all that work?" "You become rich and can live the life of rich people. They don't have to work and can spend all their time lying on the beach!"
