It is the natural way of things for a successful man to have more than one mate.
If a society tries to repress that tendency, it finds its way out anyway in the form of infidelity.
Healthier for all--society and people--to legalize polygamy.
Except that then there are a surplus of males without available women, which is not good for society. Think of all those surplus Muslim young males in polygamous societies, with too much time on their hands, and not enough familial responsibilities. Thus it should not be recognized in law, and no legal benefits should attend, unless of course an offsetting number of males are truly gay. It is rather basic really. I am surprised you missed it.
Samuel Johnson said, "The realisation that one is to be hanged in the morning concentrates the mind wonderfully."
Monogamy is like that. It helps you stay focused. More than one mate, you have congress, not wedlock. And we all know what a mess congress is.
LOL! Are you serious? So if a guy commits adultery, its really just a repressed desire to have more than one wife!? I think its a repressed desire to have sex, without the brains or moral boundary to do what is right.
Assuming that the number of women and men is roughly equal, then:
If the top (richest + most attractive) 5% of the men have 4 wives each, they're shall we say "monopolizing" 20% of the women.
Then if the next 20% of the men have 2 wives each, that's another 40% of the women.
Then the next 40% of the men have one wife each, that's another 40% of the women.
That leaves 35% of the men with no prospect of ever marrying and having families.
That's a social problem I'd like to never have to face. Since probably 90% of the people in the United States are against legalized polygamy (a figure I pulled out of thin air)---isn't that reason enough to stop it?
Or are we obliged to submit as a society to every social experiment which somebody out there finds interesting?
"Polygamy makes a lot of sense."
It sure does. Think of all the government workers, teachers, etc, who can enroll dozens of spouses in their benefits package.
There will be a lot fewer people without insurance.
