By Richard K. Vedder, The American Spectator - Not only has DEI lowered productivity and thereby the standard of living, but the Star Chamber-like behavior of some DEI administrators of campus and probably corporate dealings with managers, unquestionably, sometimes led to fear, intimidation, self-censorship, and a decline in true freedom of speech and expression. The recent attacks on the academy by governments, wealthy donors, and others are at least partly justified by what economists call the “negative externalities” associated with the growth of DEI practices that originated largely on college campuses before spreading to corporate America.
