Insistence on ethnic diversity means trouble in activities where the nature of the activity goes with radical distinctions of status and reward. Here are some examples from today’s Drudge Report: top chef attacked as “racist”, Duke professors seek to defuse anti-lacrosse team ad. The problem won’t go away. Different groups aren’t going to end up equally successful in academic life or the fancy restaurant business. Attempts to equalize results don’t succeed and only undermine the original point of the activity while adding layers of suspicion and injustice. (See this discussion of the Duke situation.) Isn’t the lesson that where differences matter the attempt to eliminate all separation and discrimination is a bad idea? If people trust each other and think they can achieve something great let them join up and work together, if they don’t let them go their separate ways and find something else. You can’t force them to be happy together.
