I know your focus is racism, but the example of professional dress got me thinking - we could probably extend the argument of privilege to types of thinkers, aptitudes, things like that. I've been looking around at the world for a while now and it seems like - specifically in this country - there is a bias towards white-collar nondescript office jobs as being the standard and things like art and performance and writing being looked at askance, as though right-brained people are somehow lesser (or open-minded people are lesser). The kicker of it is, all those left-brained people need those right-brained people terribly, and they don't even know it.
