The way you can phrase it: you may jsut get people that are happy to do a good job for the pay they get. In many areas your typical white/cis/hetero/neurotypical male is not present, because you cannot get the maximum reward for their well-trained ego. I think diversity/pay is pretty munch confounded for plausible reasons.
That's saying the white/cis/hetero male is absent because ego demands more reward. Exactly. Diversity fills that gap at lower cost. That's my point, or a counter?
The scheme's motive is the overall effect. Lower wages. It doesn't care about white hetero, or black trans who happen to participate in paralympics.
