Theodor Adorno was a German sociologist and philosopher known for his critical theory of society, particularly the divide between popular culture and true art. Adorno proposed a triangle structure to illustrate how the music industry operates for different social classes. At the top are the bourgeoisie or ruling class who appreciate true art like classical music. The masses at the bottom consume popular culture as they are seen as unable to understand true art. Popular culture aims to manipulate the masses into passivity through standardized productions. Between the classes are pop stars who present "dumbed down" ideologies to the masses and maintain the status quo, acting as puppets for the bourgeoisie.
