Is it just me or is it weird how historical manhwas depict slaves/poverty?

I hate it when I’m reading a historical manhwa and the author makes slaves or people in poverty the antagonists, portraying them as purely evil without any nuance. It also bugs me when the female lead buys one of her love interests and acts like she’s giving them a better life, but they’re still essentially a slave—just with slightly better working conditions. Honestly, in historical manhwas, I can’t stand how they glamorize royalty while dehumanizing the poor. The lower-class characters are either portrayed as saintly or completely evil, with no in-between. I absolutely love historical manhwas, but I’ll drop a story if slavery or poverty isn’t depicted with proper depth because it feels like the authors don’t truly grasp the severity of what slavery really is. Anyway, I hope this makes sense I'm just word vomiting
