I don’t think DEI is new. The original affirmative action legal cases in the 60s was in employment, particularly in breaking up the homogeneous of all-white labor unions and other all-white labor forces. Remember that the Jim Crow laws and racial segregation in the public sphere was still occurring in the 50s and early 60s, and affirmative action policies occurred in the workplace as a response to try and actually enforce desegregation in the corporate sphere.
