Like you are expressing your opinion, although I don't agree with you. Wouldn't you think that these 'rich peeps' as you call them, atracts people from other countries and them spending money in Africa wouldn't support the African economy and people working in tourism? Same for the local South African people who spend money into the economy to be able to get to the festival?
I just think there's more important things to be spending money on than drug-binges and music gatherings - Not hating at all, and each to their own :)
Trance parties aren't what they used to be anymore anyway.
