Answer:
Personally, I think that the Cinderella stories run the motif of humility and selflessness strongly. I think this because the stepmother and stepsisters' are often used to foil Cinderella with their frivolous interests with beauty and expensive clothes while Cinderella is shown to have humility and gets rewarded for it with a fairy godmother and prince.
Then, again I don't know what this question is for and it's just my opinion so take this as you will :/
Hope it helps tho!
