Gosh, I don't know what happened to that post, I will reconstruct the end:
..apart from the effect that it has, or the value we place on identical outcomes. And there is no reason we need to place value on identical outcomes.
The solution of pretending women and men have identical desires and interests is one that has been taken up by governments and capitalists not because it's great for women, families, or children. But because it's good for governments and capitalists. Get productivity up, get women paying taxes, get the value of that labour passed up the economic ladder.
One of the reasons capitalism hates work that isn't integrated into the capitalist system and remains in the family unit is because the whole effect, the value of that labour, passes entirely to the family itself. A nursery worker caring for children provides value to her employer and to the state, some of her labour is harvested from her task for those things. A mum (or dad) doing that labour in her own home with her own kids is not, the whole value of her labour belongs to herself, her kids, and her family.
