I mean I’m on your side sort of, but in the books most of the Elves do prefer having a master and not getting paid. Which one could and probably should equate to slavery.

Hogwarts is like a super prestigious job for the house elves and none of them want to be paid or freed. Although idk who their master would be technically. They sort of imply it’s the headmaster at least.

Winky is just broken after she gets freed. Or fired as she sees it. A hit to her honor, and then she becomes a drunk when they go to work for Hogwarts with Dobby, but even then Winky refuses to get paid iirc.

But yeah there’s a lot of out of context things. Fuck Rowling but I still like Potter. Not gonna give any money tho
