Antitrust law, established originally to limit corporate power, has become its friend. Think about the following anomalies:

• If a group of independent truck drivers forms an association to jointly bargain their prices, that combination is a cartel: automatically illegal, perhaps criminal. But if the same truck drivers go to work for a company that charges customers for their services on a single price schedule, there is no antitrust violation, even though this arrangement suppresses price competition precisely to the same extent. What is illegal outside a corporation is legal within it.
