Each of us is a leader, because each of us is an equal citizen. And so we see that self-interest is important, and the market is important. But they are not all. Self-interest and the market are one force in society, but they cannot be separated from another force. Self-interest and charity are one.
Every society requires charity, as much as it requires self-interest and the market.
Either we will feed the people who cannot feed themselves, or else the government will feed them. But if the government feeds them, then we will not really be free men and women. We will be lesser people, not so great as the high potentates who have the real power and do the real work. From this point of view, the invisible hand is not just the market. The invisible hand is the hand of God.
