If we can't have a more truthful world, I think I would prefer more lies and fewer delusions on the margin.
When the heroine of a dystopian YA novel uncovers the big lie at the center of her society, she wakes up tied to a chair in a dungeon, and a hooded agent of the shadow government says, "Congratulations, you figured out the secret. You will keep quiet about it, or you will regret it."
In real life, when you uncover the big lie at the center of your society, everyone just sort of sneers at you and says, "What, that old theory? That was debunked years ago! Only a stupid, evil, low-status person would believe something like that!"
