What's scary is the drop of in marriage rate, we are below replacement levels and some countries have it so bad they could soon face population collapse. I don't think it will turn around for many reasons.
Honestly?
Pardon me quoted a non-entertainment text, but Isaiah 4:1 seems to barreling towards us. Especially since the prior chapter describes our current societies throughout at least the first world countries.
Ironically a driving factor for it has been making plural marriage a felony. That plus making Adultery not illegal took away some pro family options and removed legal consequences for other forms of "sexual expression or fulfillment". There are other factors that push towards fulfilling the specific verse i quoted, but more importantly...
That's part of why i have interest in harem stories. I want to consider different ways things can go well or fall apart. Because as someone who is socially "developmentally impaired", i don't learn well on the fly.
I've already considered that "having a head wife to balance time allotment adjustments from equal to other levels with changing needs": that this could help a man avoid infighting. And at least let his heart and mind focus on loving the wife he is with, without agonizing over whether he's giving her too much time... Playing favorites... Yada yada...
It's just so much more stable to let the women ask the head wife for more or less time. The husband can still worry and even ask about why, but
whether is not his problem unless he's asked to intervene.
Sorry that this is so long. And thank you for taking the depopulation problem seriously.
