I agree with your post but this phrase caught my attention. That’s exactly what I was getting at. Everybody in our capitalist society is taught what you write there and is supposed to abide by it. It makes one think that any and all trade or service is subject to a “master and slave” dynamic and the duty to be diplomatic and “kiss the hand that feeds you”; a mindset very much alike the oppression in all sorts of organizations, church, cults, dictatorships etc.
Art is different.
Art is about self-expression and connection with the audience on many various levels, with no power play involved. Genuine thank yous are sweet but once they become a rule or duty, it’s about confinement. Real artists need to be free. Madonna is one of them, a free-thinker for the most part, and she had her struggles with it.
