How is it not liberating to not be dependant on another human being for everything?
I've seen some rather un-liberated comments above, such as "oh no! we could never make it as a family on a single income! both spouses need to work... or else!" "who can afford children in this economy? we're DINKs for life; we barely get by!" so it's rather apparent to me who is enslaved.
Actually, being able to depend on someone you trust is the real liberation.
And as terrible as bad employers might be, they usually cannot inflict the levels of physical and emotional abuse that bad spouses can. Business, not personal.
Perhaps the more equitable route is a household where both work fewer hours so both can be breadwinner and homemaker.
