Different strokes, and my point still stands - if you're going to be a slave anyway, you'd be happiest being taken care of and having as much freedom as you can get. As was mentioned earlier that you ignored, if your greatest happiness is not being a slave, then you're not a slave and this invalidates everything. Ergo, while a slave, your greatest happiness is not freedom or else you create a paradox. Instead, it's being a servant who gets all their needs looked after and allowed luxury while being treated in a positive fashion.
Also you're way, way too serious and yet also not being realistic enough. This is in another world, regardless of what year it is here, regardless of what culture, regardless of what race. That's the whole friggin' point of fantasy and fiction - the world is not ours, our historical implications
DO NOT MATTER. In that world, slavery can be an extremely common thing that doesn't necessarily have to be the worst thing - I've seen some stories where it's actually an absolute honor, like a conscripted squire's position. In that world, magic and monsters are a thing, derpy goddesses ruin peoples' lives by being irresponsible because they're a dumb loli that wants to sleep and not deal with her job.
So try not to bring real world considerations into this too much. Just enjoy the story for what it is, or don't. If you're trying to denounce that someone is using slavery positively in a story from a meta-position, just because it has negative connotations in our world, consider that you're discussing this with a black man who finds the inability to separate the two to be silly.
