I really hate the oppressed-under-class-lives-in-horrible-oppressive-conditions-that-actually-turn-out-to-be-perfect-training-conditions-for-overthrowing-the-oppressors trope.

Frank Herbert did it best in Dune. Since then it’s been done so many times and seems to have taken over a significant proportion of YA and fantasy in general. At this point it just feels like lazy writing.
