Is uncle Oscar speaking for the author when he says that paul is better off deadin the story the rocking horse winner?

Uncle Oscar's comment does not necessarily represent the author's viewpoint. It reveals his callousness and materialistic perspective, contrasting with the protagonist's emotional desperation and the tragic consequences of obsessing over money in the story "The Rocking-Horse Winner." The author uses these contrasting viewpoints to highlight the destructive nature of greed and societal pressures.
