My brother, there is nothing humanitarian about art. Starving children in Africa cannot eat art, can they? No!
There's nothing in the definition of Arts that says it should be for humanitarian purposes:
Art is
"The conscious production or arrangement of sounds, colors, forms, movements, or other elements in a manner that affects the sense of beauty, specifically the production of the beautiful in a graphic or plastic medium." -
http://dictionary.reference.com/browse/artIf you want your art to prosper and be appreciated by thousands, you need to pursue it in a commercial manner.
The greatest artists of history, including musicians, sculptors, and painters, were all comercially oriented!
If you commercialize your art, you will not need to beg people for sponsorship. People will beg to give you money!
Do you think Harry Potter, Lord Of The Rings, Star Wars, Godfather I & II, etc are not art? Is financial failure art?
