Thoughts
In my head writing an essay comparing Ron's position on house-elves with Jace's position on slaves.
There's a scene in Mull's Five Kingdoms where Jace, a former child slave, after being freed, is very rude to a slave serving them in a cafe. And Cole (from our world, was in slavery for like a month or two) rebukes him, and Mira (also been a slave for a while, also the princess, also 11 years old), is like, "he's processing the fact that he was treated rudely as a slave, you have to cut him some slack because of that."
And think some of Ron's attitude towards the house-elves is interesting when viewed through that lens. He's always been from the poor family that doesn't have a house elf, and now he's being served by house elves, and he's unwilling speak against that. The obvious difference is that Ron wasn't a house elf, but he's also not outwardly mean to house elves.
He sees no one changing the system to help him, and so he asks why he should change the system to help someone else. I think the other thing that makes the comparison interesting is that Jace and Ron are both good guys, they both are helpful and do make the right decisions. But you get the impression that they maybe wouldn't do it alone. Their loyalty is to their friends. Jace wants to protect Mira (and Mira wants to overthrow the king) and Ron wants to protect Harry (and Harry wants to overthrow Voldemort).
