I cannot speak for the parent, but I have some ideas on the matter. if one takes art to mean a narrow group of things with a narrative (specifically film, tv, novels, and radio and news stories, thus specifically excluding things like tshirts and the obama hope poster) then you can start finding examples of works designed to produce shock and contrast them with earlier works intended to invoke beauty. Star Wars is a silly, but relevant, example. the creators of the last jedi specifically wanted to "subvert audience expectations", which sounds likes "shock" to me. Whereas the first original 70s star wars just wanted to tell a good, entertaining story. To be clear, I don't buy any of the misogynistic criticisms of the last star wars film. but I did think it was a poor story. my instincts say that such a change in "art" matters, but I don't really have good evidence to show how it does. much less that the arrow of causality points the way I think it does.
