Any system to evaluate compensation would be better than the actual one, which is a completely mess that does not properly compensate artists for their work.
Currently marketing, frontstore presence and market dominance is far more relevant on a particular artist income than their craft.
Any system that actually would think about what people think about a particular craft, how much time and effort got put into it, how much it was enjoyed, etc, would be better. Currently is just about who can make more sales and get more ad money, the art is secondary and I’m being generous.
