All the best art was traditionally funded if you will by royalty or the aristocracy. Thus the artist was held to a higher standard. While all may have been able to attend the symphony or walk through the cistine chapel, it was the nobility and royalty whom paid the bills. Since the reversal of that order, the peasants have the dime and thus the art is held to their standards. If any recognizeable standard exists in their minds at all is the subject of debate. I believe it is less about the lack of audience, but the audience which flips the bill so to speak. Composer holst was correct when he said art is made for the aristocrats and only shown publicly so that they may find each other.
