What does it mean to be a modern artist in modern world?

What is Art today? Is it business, show, or some thing else perhaps?
I know many artists who successful in business, but they are not talented artists. And I know many really talented artists who live in utter misery, but they make real art.
In my mind art loses its initial meaning to be a guide to the world of harmony and beauty.
Why an artist can not be a just artist?
