The reality of the situation is that a party with 10, 100, 1000, 10000, and 100000 people feel completely different. With social dynamics being what they are it's difficult to invite everyone and still retain the atmosphere sought by the planner. I have no insight into the mindsets of the planners but I have a feeling the situation is probably the result of the realities of party planning rather than a desire to exclude certain individuals, or a class of individuals. The situation with the B-list party could probably have been handled better with regard to musical talent and an obvious discrepancy between the talent invited.
