What changed in CEO culture?

Lately, i find myself increasingly frustrated that the mass shooters, clinic and federal building bombers, and assassins of doctors, activists and queer people trying to live their lives in public have so thoroughly won in america. There is a straight line between the terrorists and murderers and people we called the crazies when i was growing up and the faction of the american right that is operating rhe country right now.

We all know CEOs suck with few redeeming qualities outside of extracting value from their employees and products, but at least twice Molly has called out specific c-suite people for doing extremely anti-racist personal activism and embracing in a legitimate way diversity equity and inclusion.

On the most recent episode she talked about AT&T board members trying to expell a nazi proposal and sounding like they were offended the ftc was forcing them to talk about it.

I wanna know if anyone has any ideas what changed between now and then. Was there a legitimately different paternal culture in the elite back then thst embraced a duty to give opportunity to all races? Was is actually less permissible culturally to be openly racist than it is now? Did business schools change, or did the source of c-suiters change from people who worked up and worked with minorities to people from business schools?

Is anyone studying this phenomenon? Anybody have any ideas? Im genuinely curious what changed in the post ww2 economy and boom from the previously cut throat and ruthless monopolists of the 20s and 30s and im assuming the whole industrial revolution if im being honest.
