Most economists believe open, honest, competitive markets are a good thing: consumers get products at the lowest prices and the most efficient producers get the sales. How to get there is another matter: Who keeps the markets honest? Any government with the authority to do that can also do the reverse. James Madison put it this way: “In framing a government, the great difficulty lies in this: you must first enable the government to control the governed; and in the next place oblige it to control itself. “
Stan Zin points out a modern version from Luigi Zingales in one of The Economist’s blogs. Luigi is concerned with “crony capitalism,” in which government is controlled by business. In his words:
There is not a well-understood distinction between being pro-business and being pro-market. Businessmen like free markets until they get into a market; once they are in it they want [to use their influence] to block entry to others. Pro-marketeers want free markets at all times.
As Madison might have said: you must enable the government to control the governed, not the reverse.
