>They think without the super-excitement from the "real fans" it would ruin the experience of the show.

i don't think it's so much about the experience of the show, it's more about the image of the artist. if only adults with full time jobs can afford to go to the shows, then they become known as artists that only responsible old people enjoy. and no responsible old person wants to see a show that only responsible old people enjoy, they want to go to the shows that the young cool people are going to.

every business does loss leaders.
