Right, but rave culture used to be the antithesis of cover prices and fancy drinks. Rave culture was very much the domain of the transient, the semi-homeless, the youth that had left their parents houses without much money. (Plus some trust-fund kids of course, but they really weren't the majority.)

So "can't afford it" isn't an explanation for the decline in rave culture, even if it might be a reason kids don't go out to clubs today.
