I have already said that this is not Miley's fault. However, I do not think there is anything wrong with writing the performer. Something does need to be done and I think that the performers can help to discourage this practice. Do you really think they want their fans to be dissappointed or to be paying such extreme prices? Maybe some of them don't care but some of them might and they might even voice their displeasure. Will it change things? Maybe not, but maybe the there will be less tickets released to the brokers and more to the public.
And, as stated, the performers don't benefit from the inflated prices. Looking at some of those prices, you have to wonder who is making more money here? I wonder how the performers feel about that. Sometimes, just because that is the way things are, doesn't mean they can't or shouldn't change.
