I don't actually know that they overtly consider themselves superior to non whites.  They reflexively think they are entitled to more because that's the culture they grew up in. It is really difficult to get them to see that as whites they enjoyed a given set of successes that most non white, and in too many cases, non male,  had to work harder at to achieve the same results.  What the rust belt is finding out now is that those reflexive expectations had as much to do with economic status as it did race.  That seems to be a very tough truth for them to accept.
