Your completely correct if you mean the norm since the 80's when antitrust enforcement was abandoned. Her stances completely align with the standing anti-laws and regulations that have existed for over 80 years. The anti-trust bar and big business have been trying to redefine what anti-trust is for the past 30-40 years which is what got us into this mess of giant firms and too big to fail economics. The perspective that bringing back regulatory action is outside the norm shows just how skewed economic thinking has been in the US.

"The norm" is doing a lot of lifting there.

Trailing historical average doesn't opine on correctness/utility.

It certainly seems "outside the norm" if you compare to the hands off approach that has been taken the past few decades.

It's irrelevant anyway, Lina Khan's views were well known at the time of her selection, this is the desired outcome by Biden.
