It’s not for lack of trying on the federal trade commission’s part. Biden admin has been fighting tons of mergers and courts keep deciding against them. We need better anti trust laws (and better judges wouldn’t hurt too). They did manage to stop a few mergers at least, for instance against Lockheed Martin trying to acquire aerojet rocketdyne holdings, and Nvidia trying to acquire Arm, and the spirit jet blue merger. And they reopened their case against the Microsoft Activision merger after they violated their court agreements. I will be surprised if the FTC doesn’t sue over this purchase of Discover.
