Well, there are white people who suffer discrimination now. "Hicks" and "bogans".
White women also face discrimination. Point isn't that no white people ever experience discrimination, more that 'whiteness' (invented over the past few centuries) provides huge advantages. There isn't really a white ethnic group, but white skin does help in joining The Club - employers won't see your skin and instinctively associate it with laziness, violence etc. And yeah, whiteness is heavily tied up with class.
