No one notices the sponging off women's free labour that men do.
They are able to go out to work, progress their careers and not bother about the domestic arrangements, because usually then mothers of their children are doing it for free, even when they too work in the cash economy.
And then they get to define the freeloading they're doing as women sponging off them, in a classic reversal.
Patriarchy, doncha love it.
