Social and political commentary by its nature, will alienate a large portion of its consumers.  The strange morphing of the definition of Art into only High Art, I think leads to the opinion of the author, and the disproportionate amount of High Art that is exclusively commentary leads to an obvious disengagement by big chunks of the population.<p>Through out history the majority of artist have been craftsman that create for the sake a client, state, or church.  Sometime in the last couple centuries working artist have become taboo, and that meaningful creation for a purpose other than that of the &quot;pure&quot; artistic value has been pushed out of High Art.<p>The fact that art the Author classifies as art, is not modern media form(TV, CINEMA, DIGITAL) seems to ensure that the prophesy should be self fulfilling.<p>I do not know of any contemporary ceiling painters.
