My take on this is there may be a correlation but not a direct causation.
In my opinion, there is a need to have A biological parent, mother OR father, in the home watching the child(ren). But not because
only a mother can provide the child attention but because if neither parent is taking care of the child(ren) there is a much higher likelihood of the child(ren) being assaulted or molested, or at the very minimum being exposed to degenerate media or ideas, or being groomed.
How many people who have same sex attraction were molested as children, or exposed to p0rnography at a young age? Sometimes even by an extended relative, like older cousin or uncle.
I dont believe it's an absolute that it
must be the woman who stays home, though i do believe in the majority of cases that is what best makes sense.
There are exceptions though, like if a woman has an earning potential many times her husband's. It makes no sense to have them live in poverty just because it should be the woman who stays home. Often these high paying jobs come with an excellent benefits package, so the new mother will be able to spend sometimes even up to a year with her new baby before returning to work, unlike women in lower paying jobs who often have no benefits.
I read this article, which i honestly found ridiculous, that had examples of high earning women who the author believed should stay at home regardless of the financial repercussions. It is not "woke" to not choose to live in poverty, and ironically these type of people are usually the ones complaining about "handouts" for the poor.
Regarding the myth that only rich white women were able to be stay at home moms, I'll just say that it's a thing to read about in college gender studies classes and virtue signal about, but does not represent reality (at least in the US).
Growing up in the 90s we lived in a working class/lower middle class neighborhood and at school literally all my classmates had a stay at home mom except for one. The majority of them were latino or first generation asian immigrants, not white. Yes, most people lived in poverty, sometimes two families in an apartment, but the women were generally not working.
Also, with childcare being so expensive it makes no financial sense for both parents to work when the net take home would only be a couple hundred dollars a month or less. "Rich" professional career women may be able to afford childcare and still have plenty of money left over, but not minimum wage workers, especially if they have more than one child.
My mother in law is always dropping hints about how she disapproves of me not working, but my husband and i know that the amount of money left over after childcare would be negligible and not worth the possibility of our children getting molested. If it means living in a smaller place and not doing things people take for granted like going on vacations or buying new cars we are fine with that. Our children matter more to us.
