Well I know you know those number are wrong, but they are very, very wrong. White people make up 80% of the USA, not 49.1%, and most affluent areas are probably closer to 100% white. Of course with billions living in poverty and globalization making those that are poor very much aware of our privileged life there will be lots of immigration, but don't worry you have a political party devoted to keeping the poor (both in your country and abroad) poor, and the rich relatively rich.
And im sure youve never experienced "white privilege", assuming you live in an extremely white area where race is relatively uniform, being white won't do much against other white people. However, you probably haven't experienced (and if you have... doubtful, but probably not very substantial) a lack of privilege due to your race, something which most minorities do.
