My knowledge on her is limited. But if she was rich, chances are that she paid people to do the domestic chores. And she had slaves which today is seen as wrong. That is, it was still "her problem" to manage the house. Since she was rich, she had the resources to pass the chores to others. But people didn't consider those chores Muhammad's responsibility.
And I get that Islam feminist is as valid as other takes on feminism. But I think that it is important to not focus just on the careers and the properties, but also on the other resposibilities like taking care of others. That is not just women's responsibilities, it is also men's. And the same pride and joy women can get fron that, men can get it. Specially with children. Changing nappies is not nice, but making sure your children are healthy and happy is.
