Ah yeah, I'd forgotten about that. Pulled up the book to that chapter, and came across this

“Can Dobby give Harry Potter his present?” he squeaked tentatively.

“’Course you can,” said Harry. “Er . . . I’ve got something for you too.”

It was a lie; he hadn’t bought anything for Dobby at all, but he quickly opened his trunk and pulled out a particularly knobbly rolled-up pair of socks. They were his oldest and foulest, mustard yellow, and had once belonged to Uncle Vernon. The reason they were extra-knobbly was that Harry had been using them to cushion his Sneakoscope for over a year now. He pulled out the Sneakoscope and handed the socks to Dobby, saying, “Sorry, I forgot to wrap them. . . .”

[...]

Dobby now handed Harry a small package, which turned out to be — socks.

“Dobby is making them himself, sir!” the elf said happily. “He is buying the wool out of his wages, sir!”

The left sock was bright red and had a pattern of broomsticks upon it; the right sock was green with a pattern of Snitches.

“They’re . . . they’re really . . . well, thanks, Dobby,” said Harry, and he pulled them on, causing Dobby’s eyes to leak with happiness again.

A boy with a vault full of gold, couldn't give his supposed friend something better than his uncle's knobbly, "oldest and foulest, mustard yellow" socks. His slave friend appreciates it nonetheless, but like, surely he had nicer socks?

I can't with this author. The fact that at the end of all of this, nothing has changed; people's worth is still determined by breeding and bloodline, the slave race is still enslaved, just kind of makes the entire journey seem pointless to me.

Oh yeah, you killed wizard-Hitler but the wizard-nazi ideology is not just at large, but commonly practised by everyone, including by the good-guy rich-orphan turned wizard cop and his friends.
