Art isn't created on a commercial scale by big corporate entities for exactly that reason unless it drives some other corporate interest (i.e. advertising, graphic design etc.). There is a subset of people who would continue to write code for themselves given no financial compensation, because they enjoy writing code. Similarly, there are people who create art purely for the joy of making art. Much as Google abandoned Reader and Alerts, don't expect Exxon to make an entry to the Turner prize.

Music has a large corporate aspect, but then a lot of music is done as art for the love of creation or the love of playing.

Healing the impoverished, for many people, is part of ones responsibilities as a human being. Everyone has the right to "life, liberty and the pursuit of happiness", right?
