Sounds complicated to me, I'm wonder how men in Arab can practice polygamy without problems there. I think a man can't be really fair to his wives in love, financial, etc.
Whether he can be fair to all his wives or not is his problem, not ours. If 90-year old Hugh Hefner is allowed to have a dozen teenage girlfriends at the same time in the United States, then why can't a 30-year old Arab living in Saudi Arabia have two wives who are in their 20s? And believe it or not, polygamy is rare in the Middle East. Only a small part of the population practices it (mostly Bedouins).
