There never wasn't room for unpaid domestic labor, insofar as cultural acceptance of the role. The economy has stagnated the incomes of so many people for so long most cannot afford, on a single salary, to provide living arrangements for such a job plus children.
There is no room in a civilized society for bondage and servitude through violence. Eudocia in this story was never given the choice until she had lived the slave life so long she was no longer able to adapt out of it, and that is fundamental to any moral discussion.
Strangely, it seems if you give people the necessary tools to have an option, ie, a public education, then nobody seems to willingly choose this lifestyle. There is no real barrier to stop someone from the street knocking on my door and asking to be my surrogate housewife for free, as long as they are doing it of their own free will.
What is important to remember is that Eudocia's behavior was conditioned through coercive violence. She never had the chance to live for herself. She was forced through threats and abuse to be the person she was, as a product of an environment that gave her no reasonable alternative. We should never wish that on anyone.
