My two cents...

Bon Jovi, Def Leppard, Motley Crue, Kiss, Judas Priest, Rush, Scorpions, Ratt, Queen, Led Zep, Journey, Poison, Foreigner, etc... FILLED stadiums and arena's...

for those 90's grunge bands and rap acts, you would need to have a boat load of acts on the bill to even come close to doing this...

point #2...
when those "hair bands" were around, the biz was healthy and money was being made... how healthy is it these days? just ask a radio station....
oh and all those employees that had jobs at record companies...
