Thanks for the answer. I think you touch on something with the Optometry example, and that example helped me to articulate a proto-idea I've been trying to get a finger on and haven't been able to grasp until now.
To avoid unnecessary anguish, pretend there's a country called Foo.
Natives of Foo are much less intelligent than the average human, and racists point to them as an example validating their racism. But imagine what's really going on is, the natives of Foo are all genetically disposed to have terrible sleep apnea, and that's what's causing their reduced intelligence.
If we ask "Why on earth are natives of Foo less intelligent?", then we can follow that thread and eventually realize it's because they all have sleep apnea. Then we can give them CPAP machines and fix the problem.
But if we dogmatically put our fingers in our ears and scream "everyone is equal!", then we have no hope of sorting the mess out. It would be as ludicrous as condemning optometry because we're afraid of hurting the feelings of people born with poor eyes.
Thanks for the comments about sociology vs. biology. Pragmatically speaking, we need to figure out how we can change our society to legitimately incentivize this "uplifting" (it isn't free). Our current tactic seems to be to brainwash people about magic pixie dust qualities of diversity. This doesn't do anybody any favors, because the invisible hand of the market doesn't care about propaganda. Push it far enough and the whole job market will be made of shell company contracting agencies whose sole purpose is to take on "diversity liability".
