It really it isn't so much about race as it is privilege (race only in that statistically a lot of white kids in the burbs are well off). If you don't have to work for anything it is hard to become good at anything while at the same time since you aren't failing at something you end up thinking you're such a super duper special person. Basically even the nice people get screwed up by being a special snowflake all their developing life.

The only part that is probably really about race is that the well off white kids are probably less likely to get told they are unhelpful idiots on these trips.
