I completely agree, from one A Little Princess fan to another. People of Becky's station were generally not allowed to speak up, as it was her lot in life to be a scullery maid, and especially with a mistress like Miss Minchin, to rebel even the tiniest bit would have ended with her being thrown out into the streets, where who knows what would have happened. I mean, that's exactly what would have happened after the Ermengarde's Hamper incident, except Miss Minchin knew that it would be hard to find a scullery maid for such little pay. Even Sara became a bit more subservient in her new station, because that's who she became. She kept her head up, though, because she figured she could still be a princess and because she recognized Miss Minchin for the hard-hearted woman she was.

To write our own morals and attitudes into a time period where they didn't exist (or weren't welcome) is completely wrong, if only because it clouds people's judgments to what life was really like back then, which in turn hampers our ability to recognize the events that brought us to where we are now.

Also, I just hate it when people mess with the history. :)
