i think what carm is saying is that she is in a position, and has the right, to not work if she wishes. its just as valid a choice to stay at home as to go out to work.
I wouldnt be her for all the tea in china, and when we retire at 65 or whatever, she will keep working until the day she dies. all under intense media scrutiny and with people pursing their lips at every decision she makes, the clothes she wears, her weight, how quickly she gets pregnant, IF she gets pregnant and all under the shadow of her sainted dead MIL.
