@J12t Amercian competition law was changed dramatically by a movement led by Robert Bork who taught that the law should focus only on business practices' impact on prices. Prior to Bork, antitrust had often addressed issues related to market power, concentration, barriers to entry, etc. Bork and Reagan dramatically limited the scope of antitrust enforcement.

Many hope that Biden's FTC Chair, LIna Kahn, will return the law of competition to its roots.
