What gargantuan investments, tbh? I've been mostly hearing of volunteer-run DEI committees and the occasional checkmark or platitude on a forum somewhere. [Not trying to be snarky, genuinely wanting to know. I haven't heard of e.g. a trans student being paid way more money for attending grad school than a non-trans one.]
If I do a DDG search for "dei chairman university", I get listings for :
U. of Denver
U. Michigan
U. Washington
James Madison U.
Texas Tech
Emory School of Medicine
U. Virginia School of Engineering
Miami University
Washington State U.
UCLA
Now, if your argument is "All this is just empty platitudes" you might be right, but it's your turn to do the research.
