Uh, it happens all the time. I could name many just in my fairly small circle of networking.When it's a black person in a position of power, it couldn't possibly be because they were (GASP!) qualified for the job. No one is going to hire you for a job you are not qualified to do. That's just not how business works. That is lost on people on macrumors.
And no, I'm not talking about minorities. Most of these are idiots are "white".
