It drives me a bit mad tbh, because at the same time that people smugly reject good literature, you can see that they're unfulfilled reading the same old dreck for the millionth time.
I think there is an unexamined craving for stimulating literature, the kind that actually provokes additional lasting thought about what is read, but that doesn't boost sales in the short term the way "My Boyfriend Is A Billionaire Navy SEAL Werewolf" or "Space Captain Murica Murderfucks The Cosmos" does.
lack of beautifully written prose that focuses on the interior life
From what I've seen, most people don't even know they might enjoy that and are just looking for some kind of perfect slop instead, sort of like a malnourished person that only has corn syrup options at a food desert might keep trying new food coloring varieties hoping to feel less sick.
