The term money has two very different meanings in popular discourse. We often speak of someone "making money," when we really mean that he or she is receiving an income. We do not mean that he or she has a printing press in the basement churning out greenbacked pieces of paper. In this use, money is a synonym for income or receipts; it refers to a flow, to income or receipts per week or per year. We also speak of someone's having money in his or her pocket or in a safe-deposit box or on deposit at a bank. In that use, money refers to an asset, a component of one's total wealth. Put differently, the first use refers to an item on a profit-and-loss statement, the second to an item on a balance sheet

Only a crisis - actual or perceived - produces real change. When that crisis occurs, the actions that are taken depend on the ideas that are lying around. That, I believe, is our basic function: to develop alternatives to existing policies, to keep them alive and available until the politically impossible becomes the politically inevitable.

Why is it that able, public-spirited people produce such different results according to whether they operate in the political or the economic market? Why is it that if a random sample of the people who read this essay and are not at present in Washington were to replace those who are in Washington, our policies would very likely not be improved? That is the real puzzle for me.
