No, in fact the opposite is true. A performer's share of the pie vis-à-vis their corporate interactions with labels has increased. That's not where the value gap lies.
The problem is that vast sums of money are pooling outside of our business, on the other side of the ledger, and it's having a catastrophic effect not just on creators but also hundreds or even thousands of jobs have been lost. That's not just at major labels. It's also the number of managers and agents. The support network that used to exist for performers has largely disappeared.
