There was a video going around on Facebook showing what happens when you ask normal work-force people and executives to work for free and they were like HELL'S NO. I'm constantly reminded that artists are often asked to create content for free or near-free but everyone - EVERYONE ELSE - gets paid: the printer, the distributor, the marketers, the internet bill, etc/etc gets guaranteed monies in their pocket while artists are often asked to take a back-end deal ("royalties") and do it for "exposure."
Better bring a coat. Too much exposure might get you pneumonia or cancer.
No one put a gun to our heads and said "You better make art or else!" But, I think doing anything else might just kill me. Only, it would take a lot longer then a well aimed bullet.
