I can't see how the practice of marrying more than one woman can end social ills, in fact it increases it. Take for instance that tv show with the one guy marrying several women. He could not legally marry them all so he would send his wives off to get child welfare because they were technically single moms - that's unfair to the tax payer. If you can only afford one wife then have one wife!
