Not everything in life should cost money or pay money, but, since most everything does, in my humble opinion art should be included. I do believe that it offers the reward of release for the artist, and offers positive measures for the consumer, but it should be up to the artist what they want to charge, and the wanting consumer should be willing to pay whatever the artist thinks their art is worth. However, not everyone makes enough money to pay for all the art they want, nor does everyone have the means to make more money. The world is a bit messed up right now, and, this being the case, it's difficult to say what we should do, considering we shouldn't be in this position in the first place where we have to decide how to salvage the art market.
My offering to those who are concerned is that you should a) be willing to pay for art that you yourself consume, b) only submit your art to paying markets if you find it to require payment, and c) offer for free or extremely cheap the things that you think everyone should have the opportunity to experience. Not all art should be for free. I repeat, NOT ALL ART SHOULD BE FOR FREE.
I don't believe that each artist is responsible for each other, and that none are responsible for the consumer. I believe that we are working with the consumer of art when we create as well as our fellow artists, so, technically every living person is involved in each transaction. At the same time, I pay those whom I work with, and they pay me; kind of like a flat-rate for different types of work deal (though it isn't always reciprocated, and I usually get the crappy end of the stick, because most people aren't honest).
For example, I almost exclusively write uplifting, positive material, and I don't think that if someone can't afford to buy it, that they shouldn't be able to experience it. It should probably be on a donation basis, but not everyone is honest, and the rich are probably less likely to donate. So I offer some for free, some for very cheap, and, for print I offer it at just about the going rate for the current art market (considering there are other ways for them to indulge than buying in print). Now, I'll charge very highly for art that I create outside of the positive, uplifting genre, because I don't find it as necessary for people to experience... it's more for fun, and although we deserve to have fun in life, as I have stated earlier in this post, the world is messed up and everything costs money, so I shouldn't be creating fun for others but be unable to pay to eat.
If your content is strictly for the entertainment of others, you should probably get paid for it, and paid well. But as far as the art market as a whole, there are many different types of work out there, and so to monetize the entire market to a certain standard, in my opinion, is unproductive and really makes no sense.
