Not everyone desires materialistic things, live performances included. I love live performances, but I think most people are not really capable of appreciating "top" live performances anyways - to them, a big mac is filet mignon.
Live performance is art, which is opposite of materialistic.
Smaller and more niche artists sell out medium sized venues in NYC, while failing to get half occupancy in fairly large cities. That is a major draw, because even idealistic artists need food.
I'm not speaking of just money and property, but rather, anything which pleases our lizard brain - this includes things like tourism, sex-for-pleasure, video games, and novels.
Some counter-examples that I don't consider materialistic are: personal relationships (family and friends), pursuit of justice, philosophy, and also creating art.
