In your infinite sanity you have not answered my question of how a creative person will dedicate their life (starting from long studies) producing something that society will not reward in any way.
In their freetime? Do you not have any? Should society reward people who want to dedicate to something that has no inherent survival benefit? Should that not be something done in ones own time?
Why is society obligated to pay artists? It isn't.
Because most people prefer spend their free time consuming art instead of staring at a wall. You just forgot that art embraces games, music, movies, tv shows, comics, books or even some Youtube.
