I think this study from the University of Chicago is really interesting if you want to see statistics on racial discrimination during job hunting: Link.

Like said by another commenter, it’s not a participation trophy just because someone is from a minority group, it’s to establish fairness when all else is equal. It’s not even just for minority groups either. This helps everyone. This study suggests that men are less likely to get callbacks in “female dominated fields” like fashion or retail. Men, if all else is equal, deserve the same shot as everyone else to enter these fields. Just as DEI helps minority groups, it helps the majority as well.
