Final thoughts because there are a couple posts that responded to me, and then I'm out because the discussion is pretty much going in circles here:
The idea that polyamory is just "fukking around" and necessarily redistributes fewer resources than polygamy doesn't seem to hold up. The idea in the West that marriage = sudden re-distribution of resources is faulty. The numbers of unmarried homeowners who are buying homes in the United States, for example,
are up. This is just one datapoint, but I could list all day datapoints that show that marriage is not the key point for merging of financial or other interests that it used to be for most couples. Hell,
common law marriages are up significantly in Canada (as well as the U.S.). Take for example a place like Quebec, specifically Montreal, where most people are coupled in ways that indicate marriage without being married (i.e. financially, taking legal responsibility for one another, etc.), as another example of how marriage doesn't mean much in the West as a way to mark when couples redistribute resources. Polyamory, polygamy, monogamy - ultimately, none of these things require marriage for the redistribution of wealth or necessities. I hope that I don't have to get tawdry and pull up examples of men and women who have paid for their mistresses or whoever's car, house, etc., but not for their own wife's or kid's shyt. There was just an article floating around here about some father of four using a bunch of his wealth to house women in exchange for sex. MARRIAGE GUARANTEES NOTHING in terms of redistribution of goods, so the difference between polyamory and polygamy is negligible at best.
The argument that polygamy undermines social and political stability in Africa is interesting. I would defer to people from African countries where polygamy is practiced because they would have more on-the-ground experience than I do with that, but I know that there isn't consensus among people in such countries about the goodness or badness of polygamy. I also note that the arguments in favor of polygamy being a destabilizing force just don't convince me when the issues with stability in some African countries are really notable in post-Colonial times. Like, if you think of the areas of Nigeria where polygamy has long been practiced, it's not like there were a bunch of unstable Igbo villages that were always anarchic or undergoing constant upheaval, at least not in my reading and learning about pre-Colonial Africa. To me, the marker for mass instability has always been the colonization of Africa. I don't think that I've seen anyone in this thread make enough of a clear data-backed argument that polygamy, as traditionally practiced, has been a consistent destabilizer of pre-Colonial African kingdoms.
BUT - I am always willing to learn, and it's more than possible that I'm wrong. I know enough to know that I'm ignorant about some things. I'm just not convinced by the arguments as presented in this thread.
Finally, polygamy in the Western world would be informed by other social movements that are less pronounced in African or Asian countries where polygamy is practiced, such as LGBTQIA+ rights/queer theory, third-wave feminism, etc. In other words, polygamy here would probably be less of a scramble for resources and more of a chance for, say, bisexual people who want a relationship with both someone of their own gender and of an opposite gender being able to enter these relationships legally. I doubt that you would actually see many people in the West take advantage of these types of relationships outside of the top 2% who might have seven or eight different wives who were never going to be fukking a dude who makes 75K a year at his office job anyway, and outside of the people who have been boxed out of these relationships legally and would love to be able to legalize them (people who are more fluid in their sexuality, for example).
This also means that it is possible that people who argue against polygamy in Africa are correct and that I'm seeing this from the perspective of a person in a Western country with a high amount of people who have different ideas about love, marriage, relationships, etc.
Sorry for the long post, but I wanted to get that out. I'll back out now.
