Raising children as a married couple in total isolation is not “family”, it’s just “atomic household unit of economic production”.
A father and mother raising children in a private, independent household separate from either’s extended family and/or parish is an invention of the industrial age. It has become normalized to the point of being considered the only real family among conservatives, who fail history 4eva on this particular front.
There are a number of folks in the far end of right-conservative land who talk a great deal about how such and such a ‘european’ ethnic group has ‘always’ had nuclear families, but this is just a sign of how poorly educated they are about their own ethnic histories.
The pioneer family model wouldn’t exist without a lot of technology. In some very real ways, the Ingalls/Wilder pioneer family is about as modern as families now in terms of sheer social isolation and dependence on the nuclear family for emotional needs to the point of neurosis.
The shift from clan to family to “extended” vs. “nuclear” family is just tracing the steps of technology and modernity and insane amounts of wealth in tearing us all away from the real forms of kin and kith.
Also, defining family in terms of the nuclear structure saves a lot of people the trouble of being held to account for their obligations and responsibilities to their familias/clan/bondsmen/etc. Webs of intersecting authority, hierarchy, devotion, obligation and love. Those are lost today and to get them back for the supermajority would require a lot of people to stop egotripping. WOE.
Anyway that’s all I have to say about this right now.
