I agree that the best of the best should be hired, but there's a lot of advantages whites have over other minorities in the work field (including privilege, education, socio-economic background, and opportunity). There are some minorities that simply won't have the opportunity to become the best at their field simply because of their race.
You're saying that someone will have more or less money and privilege just because of his race? If Apple wanted to go out of their way to hire people from low-income families, they could do that rather than making assumptions.
Oh yeah, and Arabs count as white or Asian. Consider where some of them are coming from and what's going on there.
