If I said that there was a quality that all black people have that prevents them from being as successful as other races - but they can't see it because they are black, only other races can see it- I'd be called racist and have my house burned down.
But Oprah can say that white people have an advantage that makes them always more successful than any other race - but they can't see it because they are white, only other races can see it, and that's not considered racist?
I have a feeling that it has nothing to do with her being rich. It is just racist.
