Practically all government attempts to redistribute wealth and income tend to smother productive incentives and lead toward general impoverishment. It is the proper sphere of government to create and enforce a framework of law that prohibits force and fraud. But it must refrain from specific economic interventions. Government's main economic function is to encourage and preserve a free market. When Alexander the Great visited the philosopher Diogenes and asked whether he could do anything for him, Diogenes is said to have replied: "Yes, stand a little less between me and the sun." It is what every citizen is entitled to ask of his government.
