Show me where any of this led to any mergers or acquisitions or caused people to lose their jobs? And, you might not be up on this, but one of the big proponents of DEI/ESG was the head of a little investment company called....BlackRock.
Individual companies are free to do whatever they want. I'm not sure your point here.
And that started long before Gensler was appointed head of the SEC. And, I also hate to point this out, since capital markets do not exist in a vacuum. A little group called the European Union (along with a number of Asian organizations) have embraced ESG, which does include strong support for DEI. So, the point of all that is that the SEC was at the time making it easier for American organizations to comply with international laws.
As long as I can remember, Europe has had more and different regulations. U.S. based corporations are quite adept at complying with local regulations without mandating compliance across the entire enterprise.
Gensler might have thought this would help standardize practices across North America and Europe, but that is a political judgement. The SEC has no mandate to require or even encourage ESG in the U.S. It is an implied threat that is no different than what some people say Nextstar is responding to with the current Administration.
The problem with your analysis is that you want to ignore the deemphasis in ESG since Gensler's departure. Now I would admit Gensler's departure is not the only reason for the change in Corporate mood over ESG. However, if companies went to court to fight the SEC's climate reporting initiative that is the definition of regulatory pressure resolved by the very definition of conflict. Why go to court if it was merely suggestive guidance?
So...show me ANY company that got in regulatory trouble for not following DEI? Or one where the head of the SEC threatened them with something for not doing it.
Who said the Nextstar merger was in regulatory trouble? That's liberal conjecture to fit a narrative around KImmel. I personally doubt that it is or ever was. A pending merger doesn't explain Sinclair's action. Sinclair is just exercising its rights of ownership. Pretty much like your BlackRock example.
In closing, as I said people tend to defend inappropriate government intervention when it suits their politics. It can be rationalized. The SEC example was only just one. Facebook said it was "asked" to suppress the Hunter Biden laptop story. The Obama and Biden Administrations encouraged the debanking of politically unpopular industries.
There is always subtle political pressure applied by many regulatory agencies. The heads of these agencies tend to be very political and that's how they get appointed here in the U.S.
