Ah, the tautologies economists weave. Professor Gary S. Becker's argument that the market should be the judge of Microsoft's marketing practices, not antitrust enforcers, assumes away the question ("Let the marketplace judge Microsoft," Economic Viewpoint, Apr. 6). The question is whether Microsoft's market power is being used to displace competition. The antitrust laws are a principal element in defining the scope of Microsoft's property rights.
Letting the market sort out the effects of Microsoft's practices when the question is whether the market is being disabled from doing so is at best a silly tautology.
