I can see that there are 2 distinct layers with both composers and producers (I'll use the term "producers" here as anyone who makes films). You've got those who make music (or films) as a hobby, and those who want to make a living out of it. And, of course, there are loads of variations in both camps for talent, focus, ability, etc. etc.
It's easy to confuse the hobbyists and those wanting to earn a living at an early stage in their development - both tend to work for free, both can do either great (or bad) work. And I fully agree with Goat that throwing money at someone who hasn't got "it" (whatever "it" happens to be defined as at the time) won't improve things.
But those who want to earn a living reach a point where they have to start charging. Why? Because they want to give up the crappy job they've got that keeps body and soul together, and actually do their work AND pay the bills (and, certainly from my point of view, re-invest that money into better equipment which will improve my work).
I think it's probably fair to say that the same things happen to producers.
Likewise, I would never think of charging a producer for music for their film
if they haven't got any budget. It doesn't help them or me.
Wow, didn't mean to go on for so long. Just my 2cents worth!
Personally, I think more dialogue like this between composers and producers can only help us better understand one another.
