Barriers to entry, the centerpiece of antitrust intervention in the market, is a doctrine seeking to live beyond its time. Having been tried and found wanting as an economic concept, it is now trying for a new life under the rubric of fairness. Some are arguing that anything that makes entry into a market difficult is unfair, and that government has the responsibility to eliminate this unfairness. Central planning becomes inevitable once ethical values such as fairness replace economic efficiency as the goal of economic policy.
