It's sort of implied in your comment that black Americans have the same access to the superficial perks the person you were responding to suggested.
Here's a simple thought experiment for you. If you took the starting rating, x, for a set of Americans, I think you'd find that whites have a higher initial starting rank than someone who's black or Hispanic. It's harder to climb the ladder when you start out on a lower position.
I think that thought experiment starts from a flawed premise. There's no starting rank for a set of Americans - different people have different starting ranks.
Obama's daughters start out well ahead of a homeless white boy, for example, and any bias that would lead to aiding Obama's daughters instead of the homeless white boy is unjust.
