It's reasonable to think that there is (A) some correlation between parental income and intelligence. Also, it's reasonable to think there is (B) correlation between parental intelligence and their children's intelligence, which in turn (C) correlate with school performance.

So yes, maybe people in the low income group are "inferior" in the sense that they'll have a harder time in school, because they are (on average) less bright. Everyone knows that some kids have an easy time in school because they are quick-witted, and others will have a harder time.
That's not saying we shouldn't try to help them, we certainly should! But I think we'll make less progress on that goal if we cannot admit that some kids will have a more difficult time than others.
They don't see the value in hyping up ethnic/racial identifies. It's a difference of values / philosophy.
And inferior is loaded language. Success in something does not mean those that aren't are inferior.
Sweeping group level decisions ultimately affect individuals.

Why not?
Progress isn't exclusive to the left, and people offering progress often destroy rather than improve. Progress doesn't necessarily require sacrificing meritocratic ideals to satisfy some sludge of totally-not-marxist, totally-not-postmodern, totally-not-intersectional, totally-not-critical-theory thought. We can make everyone's life better through other methods. I'm happy to see the zeitgeist finally getting over this fixation that politics is described by "The Good Guys vs the right wing".
My idea:
Judge people on their individual merits and whatever happens is fair game. Implement a social safety net to prevent people from suffering. Reparate historical violations of the first tenet. Aggressively target monopolies. Increase environmental protections. Increase transparency in business and government. Increase education about our financial system, personal finance, and contemporary topics.
These ideas can be easily composed onto the ideas we already have, will result in benefit for everyone, and the political distance between them and the common man is much less than it is between all the woke stuff.
If there is a statistical difference in outcomes, why? Is one group inherently inferior? Or is there maybe not the equality of opportunity that they claim?
