She is just more subtle about it, beautifying herself no differently to her hostile sisters, using make up and a dress to turn the head of the prince, attended the ball for the same reasons and pretended to be a noble in order to get in, even though the ball was open to commoners too, she did this so the prince would feel no embarrassment making herself more available to him as a compatible option…
When the prince finds out that she is a slave girl, she says…
Hypergamy at its best, notice she says “who loves you” and not" in love with you"…it would of been more believable if she had said that instead…notice how she uses the words “country girl” to softly highlight her poverty and slave role making herself seem more creditable…and of course she would have to put the word “honest” in front of it for that extra boost…
Well that explains that. In the original she is the daughter that is noble of mind and yet a lady. The prince was noble of mind and a gentleman. Dignity was in the original. The story was designed to give hope of true love against the odds for both boys and girls. Though it was taken and made more for girls when Disney got hold of it. Disney did balance occasionally but, the late 50s and 60s were about social change. Walt took advantage and used stories to educate.
You are quite right about that but, we first need to find out if there are other stories with near or so many versions. Then dissect and decipher the whys , what’s and who. Off hand , different societies would require different versions. But, why adapt?
