Once I was at a meeting when a musician said "I wish, just once, a record producer said 'hey, we made more than we expected on that project - here's some extra bread' ". I said I'd be happy to do that AFTER I heard a musician said "Hey, I know what you were trying to do, and it just didn't work out - here's some bread back".
He laughed and gave me an elbow in the ribs.
Please note, I understand your complaints. They are valid, but are the same for all "art driven" folks.
