One of the quotes I so often see out there (in creative circles, anyway) is that art saves lives. Which I believe is true both in terms of the observer, and the artist.

Growing up in Denmark (1970's) was different in the sense that art there is for everyone, not just for rich people. More specifically, meaning that your average plumber or retail cleark is just as likely to consider art "important" as those upscale people who can really afford it. As you said, Van Gogh's work was for the common man.

My own art is also very "niche," and I am looking for supporters and appreciators more from a spiritual awareness angle than from a financial demographic angle. I'm more likely to have a good weekend as a vendor at a UFO/Paranormal conference than at an Arts & Crafts show... and I feel really appreciated and seen by the "tinfoil hat brigade!"
