We believe that what we possess we don't ultimately own. God is merely entrusting it to us. And one of the conditions of that trust is that we share what we have with those who have less. So if you don't give to people in need you can hardly call yourself a Jew. Even the most unbelieving Jew knows that.
Much good art got made while money ruled I like a lot of it and hardship and poverty aren't virtues. The good news is that since almost no one will be selling art artists - especially emerging ones - won't have to think about turning out a consistent style or creating a brand. They'll be able to experiment as much as they want.
