The moral is, Ari Aster is deeply afraid of people and can't connect to a world of people driven by self interest. I think it's genuinely bold of him to share these stories (particularly this and Beau) in an era of "cringe culture" where everyone is supposed to be cool and have shit figured out. These movies remind me of Robert Crumb comics where it's like "okay, you didn't have to be THAT open about the inner workings of your mind," but I want away glad the artist did, and impressed by their technical skill.

I would also say that I don't think the movie is about* covid or politics in the way that Shawshank Redemption isn't about * the prison system, prison is just a backdrop against which the character study takes place.
