The great virtue of free enterprise is that it forces existing businesses to meet the test of the market continuously, to produce products that meet consumer demands at lowest cost, or else be driven from the market. It is a profit-and-loss system. Naturally, existing businesses generally prefer to keep out competitors in other ways. That is why the business community, despite its rhetoric, has so often been a major enemy of truly free enterprise.
