As Burdick states, the representative artist produces far less product for a gallery to sell, than an abstract artist does. So it makes better sense for the middle men in the art world to promote abstract art rather than representational.
Decoration is right. The crime is, this fad decoration has been pushed on the public as worthy of the same deep respect, and as worthwhile an investment, as quality art. I am absolutely THRILLED that my generation and younger is finally standing up and saying the Emperor is naked.
