>Having a black doctor for a parent probably provides more benefit than having a white dockworker for a parent.

Sure, but having a white doctor for a parent is very likely more beneficial than both of those examples. This should not be a very controversial point.

Yes being white and rich is better than being black and rich, the point is about where benefit is coming from. The idea is that being white and rich is better than being black and rich but being black and rich is much better than being white and poor. Race, gender, all these things play a role but their influence is totally swamped by the influence of class.

Your argument would only hold water if distribution of wealth were independent of race. On the contrary, it is intimately intertwined with it. Race is the fundamental foundational rift that the nation constructed itself on, and it had better bring its primary focus to it.
