Lawmakers say there is plenty of blame to go around

Lawmakers and academics agree: They have not done enough to curb major technology companies from rising to dominance.

On Capitol Hill this past week, lawmakers accused the Federal Trade Commission and the Justice Department of letting the companies off with wrist slaps and pressed them to be more aggressive. And at the University of Chicago, where academics have for decades set the tone for antitrust regulation, one professor has been wondering if they got it wrong, my colleague Daisuke Wakabayashi reported.

Regulators and researchers were unprepared for the rocket-ship growth of Facebook and Google, and the companies have successfully argued that they’re providing a benefit to consumers by offering services at little or no cost. Historically, that has been enough to keep them out of antitrust trouble; regulators usually look for signs that monopolies are exploiting their power to skim more money from consumers. The University of Chicago helped shape this ideology, while the F.T.C. enforced it.
