Well… yeah April, but…..
1. There is more than a danger that the small world of “experts’ will suffer from inbreeding. Or the results of inbreeding. Too many parents inseminate their young in the "art-expert" world.
2. There is a tendency for the majority of “experts” who define the existence of, and the importance of, art to not themselves posses the ability to create it.
3. There is a circle of economic dependency that develops around and among the “experts” to create and sustain income flows from their product… art. So that; critics, academics, art historians, curators, gallery owners/managers, collectors, framers, craft industry manufacturers, media people, and others are all part of subjectively defining their own value, their own worth… By that I mean this closely protected circle defines the “art” which creates the value which supports them all. Note… that artists are the fodder of these people but is rarely among them. It’s the Circle of Life… at least in a lot of schools of arts and humanities.
- It is written in the I-Ching that, “Whether there is food in the kitchen is not decided in the kitchen.”
Look, I edit and am a partner in a pretty influential magazine business. Guess who decides who is the art critic for those pubs? Guess who decides what the motives are for that critic? The mission? And in this case, the person who ultimately makes that set of strategic decisions has no "expert" certification of any sort…. Me.
4. One thing everyone agrees is that the art industry is about a subjective result. That’s a whole lot different from say the economics biz, the chemistry biz, the engineering biz, the accounting biz, the automobile biz, the … well you get my point. Whether an economist’s prediction is accurate or “good” can be rigorously tested… outside of the economics profession. Ditto the physicists. Most fields create their product but its value can be rigorously evaluated by the common man/woman in its use.
5. Art is one of the few fields where only a priesthood can judge… define… rank… evaluate… the product… and as I pointed out, few of the priests (“experts”) are themselves sometimes craft workers, but rarely acclaimed artists. That is a tad odd, no?

This whole art thing is a puzzlement wherever you poke at it, huh?
