High art – i.e. real art - like Booker prize winning novels and Beethoven is objectively superior to junk entertainment like Piano Tiles and most reality TV. Some egalitarians of taste dispute the existence of any objective distinction in quality between pushpin and Pushkin because, they claim, the value of anything is merely the subjective value people put on it.
I will humour them.
The case for the objective superiority of art can be made entirely within a narrowly utilitarian - ‘economistic' - account of subjective value, because in the long run consuming junk entertainment is less pleasurable than consuming art. Art is the most efficient use of your time.
