Ironically I think people focus on the happy ever after bit of fairytales rather than the grimness that leads to someone getting and accepting magical help to overcome this. Of course in our world it isn't magic that helps people (other than perhaps what could be called the magic of human kindness).
I always picture fairytale worlds as being colourful and noisy. (It wouldn't have been that quiet in Cinderella's household with the stepmother and ugly sistes complaining at her all day long). Would I want to live in a fairytale world? No. Just as power can be abused by us, there's nothing to stop magic being abused and I certainly wouldn't want to be on the receiving end of that.
