Some of you are a bit naive it's not even funny. Have you look at the census lately? Or maybe a research on the differences in races lately?
The fact is: we're not all the same. Obviously, there was a "headstart" for the caucasian. Obviously, there is an advantage being a male over a female, etc.
Don't believe me? Check out the pay averages in many different fields for male vs. female, white vs. the rest.
(take a couple of sociology classes and see how "equal" we all are)
