That's largely the systemic problem with joining certain professions. Those are most often the qualities the market seeks, but education and experience are biased towards the wealthy. You need resources to attain them. For historical reasons, non-white people as a group don't have the same kind of wealth.
I expect at the end of the day they are one and the same. As in, certain races are treated the way they are because they are poor (generally speaking). It is not like, for example, the white "slack jawed yokels" (rednecks, hicks, white trash, whatever insensitive term you want to call them) are held in high esteem. They too are poor (generally speaking), so they get treated poorly.
Let's face it, if the rich list was comprised of mostly black women, we would be bowing down to them and praising their every move. They are marginalized because they, by and large, don't have a good answer to "But what can you do for me?"
But do they? Adjusting for education and experience? I've yet to see proof of that.

I can attest to it personally. Not proof, but it makes me wonder.
