It will be interesting to see how people spin this particular one.
Having made that comment, I have to say that I think it depends on who equates "Cinderella" with the "work side" of the character and/or who, instead, primarily equates the character with having to deal with the aggressive behavior of others ("step sisters"/"step mother") who are out to make sure that Cinderella doesn't get to "the ball".
My mother came from a family of five kids who survived from birth into adulthood. (My youngest aunt's twin died at, or shortly after, birth).
The siblings in their family were five years apart (except for the one brother, my mother's twin).
My mother saw herself as a "Cinderella" because the eldest sister was ten years older than my mother, so she was off and married with two kids by the time my mother was, say, in her teens. There was another sister who was married and widowed, and had a child, at around twenty/twenty-two. So those two older sisters were both into their "grown-up" life when my mother was in her teens. The only boy in the family was a boy, and in those days (and even in some families today) people didn't expect the same kind of work/helping with caring for family from boys as they did girls.
So, there was a time when the two eldest had their own thing going (and the one with a living husband was all wrapped up in her own situation); so their mother expected/needed that eldest of childless girls (my mother) to take on work/responsibility (especially when the mother became ill and was bedridden before she died).
Of course, I imagine who took on what work may have shifted or been shared at times; but even with that, the eldest one had a husband and a couple of little kids (and whatever challenges of her own she had to deal with); so I'm just not seeing her as "Cinderella" when my mother was a teen and early twenties. Maybe her turn at being Cinderella ended when she got married. (Getting married can pretty much be one of the quickest ways to end being a "Cinderella" (lol). Oh wait... Then there's the thing that so many men think the housework and kids are "women's work) - but that's a Cinderella problem for another time.)
Keep in mind that the most self-centered people (whoever that may be) aren't likely to view things through anything other than their own eyes/place (in the family or in the world).
