I was trying to be subtle about it but now that you asked I'll spell it out.

The explanation he is looking for is "racism is everywhere" which implies the call to action that "fighting racism" is the purpose of all "good people"

The real explanation is that darker skinned people tend to have worse outcomes than lighter skinned people is because darker skinned people are less intelligent, have a higher time preference, and have worse impulse control.

This explains every "disparity" but nobody in a western country who works for any significantly sized institution can give this answer and expect to keep his job.
