Because voting with your wallet is nonsense, we can decide what society we want to live in we don't have to accept one in which human artists can't make a living. Capitalism isn't a force of nature we discovered like gravity, it's deliberate choices we made.

Or would you prefer these things be outlawed to increase employment?
