Alas, many people enjoy victimhood. They embrace being "outsiders." Look at the Christianists who insist that they're a persecuted, victimized minority. Look at people playing more-victimized-than-thou. I've been known to fall into that trap myself.
Look, Worldcons are an expensive hobby. I'm a white, middle-class, well-educated American, with a good-paying job. That means the hobby is accessible to me in a way that it wouldn't be to many others. But there are many hobbies that aren't accessible to everyone. Ever priced season tickets to a professional baseball team? (I could probably afford season tickets to the San Jose Giants, but not their parent club to the north. However, I can't (or more accurately, won't) afford the time.) The fact that some things are too expensive for you or me to afford doesn't invalidate their existence. I can't afford a seat in that restaurant overlooking the course at the Monaco Grand Prix, either, but that doesn't mean I have a valid case for demanding that the race either be canceled or they give it to me for free.
OTOH, as a white, middle-class, well-educated American male, maybe I'm just so privileged that my opinions are meaningless. Sorry if that sounds like whingeing. Give me credit for at least being aware that I know I've got it good and that it might color my attitudes.
