The statement made earlier that many of the most famous Renaissance artists were "subsidized" by popes and emperors overlooks one important fact: those artists had already established themselves as people of real talent in the private sector. Popes and emperors did not hire artistic bums; they wanted only the best. Pop art would not have appealed to them: that's why Michaelangelo was chosen to paint the ceiling of the Sistine Chapel, and not Michel Tortellini.
In my opinion, one reason so few "modern artists" follow the old classical school, is because they do not have the math skills necessary to paint a scene using correct perspective. They lack the discipline to devote themselves to a painting that takes weeks to complete.
The same lack of discipline and paucity of knowledge about music and its timing, is one reason so many modern musicians cannot compose a lengthy musical piece without making extensive use of codas, codas with key changes, choruses with codas and key changes, and every ending up an octave and LOUD.
Art should, thus, be unsubsidized by the government....that way, if it doesn't appeal to the masses or to some wealthy patron, it will die a swift death.
