Current way things are run includes getting people to work for free. It was always that way for fine artists, as we'd be expected to do ludicrous amounts of work for free because 'you are an artist so you like doing it.' Now, however, the concept has been vastly extended.

a few days ago i was listening to a teacher in the USA complain as they always do that they should be paid more because their job is important and they are highly educated mostly. i was nodding yes yes as i have always believed that and then LIGHTBULB!!! it SUDDENLY DAWNED ON ME how many people i know do work that does not pay well, because it is what they want to do! or because they want to live here instead of, say, New Jersey! so now i am wondering should teaching be any different?
