In Western culture, polygamy is generally considered immoral. Is there sufficient justification for this classification? Can it honestly be said that polygamy is wrong? I don't only mean one man/many wives but all the various possible arrangements of multiple partners, for instance one woman/multiple husbands, multiple husbands/multiple wives, etc.... There are some economic advantages to multiple adult partners living together. Take for example a situation where a man has two wives. The man works and so does one of the women. You now have a dual income household. The second woman does not work, but instead stays home and cares for any children and housekeeping duties. What would normally fall on one woman (working, housekeeping and child-rearing) is divided between two. It is assumed that all parties are consenting adults who consider themselves equal to one another. This has the added advantage of reducing the child day care costs so often frustrating for households with just two parents who both work.
