U.S. courts evaluate antitrust issues very differently, nowadays, than they did a hundred years ago, just after antitrust laws were established to keep big corporations from abusing their power. Back then, judges tended to be largely concerned with protecting suppliers from being squeezed by retailers, which meant that, if a corporation exercised monopoly power to push prices down, hurting suppliers, the company could easily lose an antitrust case. But by the nineteen-eighties, the judiciary’s focus had shifted to protecting consumers, leading courts to become more prone to ruling in favor of the corporation, on the grounds that lower prices are good for consumers.
