given the context of the article, I'm not sure why you're being downvoted.
If your entire social and economic network is built around the totalizing influence of (the conservative end of a) religious institution, and if that institution says that women should stay at home, then there's a de facto barrier to full participation in the labor force. So, the stay-at-home parent will be the woman.
Fortunately, there's a "way out" that there wasn't in previous generations: "just" leave the church. Unfortunately, saying that's far easier said than done is the under-statement of a century.
