My money is on the identitarians. "Driving While Poor" is not a thing. And there is no reason that Black people should not aspire to being entrepreneurs and capitalists. One must make the additional Marxist case that a classless society would not feature comfortable apparatchiks and a poor population. There is no need for racism in a worker's paradise, because there, everyone's like sucks.
Poverty is the natural state of things because all species multiply until there is too little of what they need. Human ingenuity, pace Malthus, has enabled some societies to stay ahead of the curve, finding better ways to produce goods and services as their population grows.
History teaches that the most effective, and perhaps the only, way to keep production ahead of population growth is to reward the people who organize the most appreciated production with wealth. Even if a different distribution of outputs might be preferable, no other method of distribution results in as much to distribute.
The material claim of capitalism is that, even after capitalists' claims are satisfied, more stuff is available to everyone else than under any other system of production. The case against capitalism, then, is not that it distributes outputs unfairly, but that it creates fewer outputs for workers than would be available to them under some other system. That case has never been made, because no such other system has ever been created on a large enough scale to matter.
Why, then, should Black Americans also be Marxists? Marxism offers egalitarian poverty, hardly a step up. No, Black Americans are right to demand access to capitalism's chances. If successful Black Americans choose to use their wealth to benefit their own - have you heard of the UJA? - that's their privilege. But working class Whites are the ones who feel most threatened by Black equality, and the idea that they have some class struggle in common strikes me as very wide of the mark.
