This is the trouble. If one believes that material leveling is tantamount to justice, then it doesn't really matter whether one group is lifted up or the other is reduced.
Your argument (A) implies that by raising one group another is lowered. Another poster here (B) states that if we can't raise one group, we must lower the other.
These are both Manichaean positions that obfuscate the mutual gains added to economic society when one group is raised and the mutual losses sustained when one group is reduced. [The counterpoint to both positions is "A rising tide lifts all boats".] I'd argue they both arise from a sense of group identity that is anathema to both universal identity and individual liberty; at root they are the pathologies behind (A) fascism wherein the group identity is based on a threatened victim race and (B) communism where group identity is based on a threatened victim class. That's why switching from one to the other is so easy; they're both simply material grievances, elevated through propaganda into mythic group struggles.
