To clarify: im not saying that Torah says women should never do any work that a maidservant would do, quite the opposite and that is one of the main ways she endears herself to her husband and they have great sholom bayis – its by serving him in various ways.HOWEVER he for his part greatly respects her (more than himself as the same Rambam you quoted above goes on to say) and treats her like a queen and equal.
I think a great example of this is Rabbi Akivas wife Rochel. She worked really hard, in extreme poverty, and then raised the children herself did all housework etc while her husband left to learn for 24 years. However he made it clear that all the Torah he and his students had acquired was in her merit and he bought her a golden crown as soon as he could afford it to make up for the difficult times she slaved away. This represents the ideas above.
