The globalist elites have a problem they must continually solve: there are a lot more of us then there are of them, and they have to keep us from noticing that.
A tried-and-true strategy for doing this is divide and conquer: if they can convince half of the poor and lower middle-class population that their real problem is the other half of the poor and lower middle-class population, and vice a versa, they are good to go.
And thus we get the twin memes of "white privilege" and "welfare parasites." The function they serve is to help convince poor black families in the South Bronx that their real problem is poor hillbilly families in Kentucky, and vice a versa. To the extent these two memes take hold, they block the possibility of a true populist revolt against the rule of the current elite.*
Of course, many, many people sincerely buy into the ideological superstructures being erected to support elite rule. The fact that they materially benefit from their subsidiary positions in the ruling class helps in this task tremendously: largely, this support army consists of university professors and other educators, government bureaucrats, mid-level corporate managers, and so on: people who are materially very comfortable within the current system. But most of these people are not cynics, and they must be led to believe that they are truly working for a noble cause: this is called false consciousness. Its spread is helped greatly by the knowledge, trickling down from the top level of universities, corporations, and government, that anyone who calls into question this schema risks ostracism, loss of opportunities, and other serious career and social consequences. It is much easier to believe an ideological construct when, in the back of your mind, you anxiously recognize that failing to believe it can cost you your job or your next promotion.
Interestingly, as I understand it, many old-school Marxists recognize this dynamic quite well, and are contemptuous of identity politics as a result. The fact that many of their younger colleagues have embraced this tactic shows that our current elite is clever enough to co-opt even Marxism in its interest.
* I am not a Marxist to the extent that I am not a utopian: I think all societies have some elite class. The problem with the current elite is their lack of any moral compass other than becoming even richer and even more powerful.
