I think its like anything when it comes down to money, especially with the big names.

At the end of the day, DJs are only worth the money people/promoters are willing to pay. If they are too much for what they bring to the club night then after a while, promoters will stop booking them. The DJ then probley will have to lower his/her fee to get gigs.

If the scene dies out then no money for any DJs so it sorts its self out in the end.

Money always ****s up dance music scenes but pros need to earn money like anyone else.
