Not necessarily. It could relate to groups on top and those on the bottom.
And why are some groups always on the top and some groups always on the bottom? For example, in academic aptitude and IQ tests Asians and whites always average higher than black people. On the other hand, black people dominate the Olympic sprints. Isn't it possible and even likely that race is a major (if not the major) factor in those outcomes?
Why then can't we look at certain groups always occupying the lower tiers of various societies and say that their genetics play a major role in that outcome? It would defy both evolution and logic to acknoweledge that the various races evolved for millennia apart and acknowledge differing physical characteristics and biological characteristics (predilection to certain diseases), but then completely dismiss the idea that evolution likely resulted in differing average aptitudes and predilection toward violence among the races.
The idea that race doesn't matter is a new idea in the scheme of world history. It contradicts statistical, anecdotal, and historical evidence; and is grounded in the politics of trying to create multicultural states more than it is science.
