Polygamy will always be constrained by the fact that no man wants more than one mother-in-law. LOL

Heck, you knew this was coming! Its not a real factor. You can marry as many partners as you want now—just one at a time. Just ask Trump. Now you can have more. Many famous people live in threesome arrangements in secret. Now its open. Next will be Legalization of Prostitution (and taxing it). The oldest profession can be made formal. Sex worker unions are coming.

I suppose you could marry sisters...or brothers...or brothers and sisters...
