Donald Trump made good this week on his promise to ban the race-based preference system formally known as diversity, equity, and inclusion. (He is likewise moving forward with his pledge to—yet again!—pull the U.S. out of the Paris climate accords.)

Trump is hardly alone in his disdain for D.E.I., whose web of strategists, consultants, program officers, and training curricula collectively constituted a $7.5 billion industry as of 2020, according to a 2023 report by McKinsey. Billionaire Bill Ackman and indie-media mogul Bari Weiss made dismantling D.E.I. almost personal crusades as reports of anti-Semitism surged on Ivy League campuses.
