I’m not sure what the writer’s point here is. He seems to be saying that art is something that takes a lot of effort to do well, and that some people don’t appreciate that.
He then implies, but doesn’t actually state, that this lack of appreciation leads artists to get paid less money than they might otherwise get. He makes this implication in the context of saying that artists need to make some of their art free in order to get noticed.
I can understand that. What I don’t understand is whether he’s trying to resolve his argument in some way. Does he mean that unless people appreciate art more then artists will cease to make art?
