Nono. you didnt understand. At a certain point, musicians and producers are not 'better' than others.. They are just different. But to get to that point, a musician needs to train hard their entire live. Once they are at that point, they are essentially normalized. And the 'money' this, is just the way it is. it really is best kept as a hobby. :)
Oh.. yes.. the producers are typically more talented. Not always of course.. really depends.. but it is in the same way a teacher would be more talented than a student. There are studio musicians who are very talented, but they are also people who work for pay. So say a singer, who writes some songs in her spare time and has some friends say she is good at singing Karaoke.. saves up some money and goes to a studio .. She is not at the same level as somebody who does it professionally for a job. The point is .. there is a separation between Professionals and Clients. That is what I was meaning.
And honestly, clients can be ANYTHING. Sure, maybe 1 in 20 is very good and rewarding to work with.. But 19 in 20.. are not. And it isn't only that. There is a lot of variety of jobs .. like recording Commercials, and Math Question voice overs .. or who knows.. Every time you hear anything, somebody needs to produce it.
