I think that's a good point Bath. I want to talk more but must walk to the shops, but as I quoted earlier from "The Meaning of Wife" byu Alex Kingston;

Legislation has freed individual women from the shackles traditionally associated with the role of wife. Yet the need for the wife has not been removed from corporate, economic and political infrastructures. It is as if the wife has been left by the roadside (circa 1965), her important, if invisible, social and economic contributions marginalised. Women assume they have been freed from wife, but wife hasn't been freed from women. Individual women may have been untethered from wife, but the structural need for a wife remains entrenched in the culture; and this, in turn, remains tethered to women like an invisible anchor.
