Much of that stay home is slavery is based on the doctrine that divorce is inevitable, that no marriage is permanent or a partnership.
It is part of the left wing "vision" that marriage will evolve into a temporary "contract" and that children are for breeders and not actually part of marriage.
The leftists (insert democrat or socialist or communists) can not infultrate or take over as long as husband and wife remains a term with meaning, or even the words mother and father. Notice how the MSM avoids the word mother and father in favor of the androgynous "parent".
And it's always "working parent."
The fact that a mom puts in a 40-hr. workweek, plus 60 hours of OT means nothing because we aren't earning the bucks.
