While I would also pump the brakes a bit on any particular effort, the Biden administration is pushing back against the dominate thinking of "antitrust bad" that emerged in the 70s. I believe he's made a lot of appointments reflecting that, which hasn't happened since the Carter administration.
What kicked off that shift? Robert Bork's 1978 book The Antitrust Paradox, which is yes that Robert Bork. I honestly think people could use more knowledge about the sausage is made when it comes to government.
Supervisor cats would also like to remind you to replace the flapper if you don't know how old it is.
