Polygamy

[Duke of Gloucester]

Multiple emotions to contend with, the group empowering effect some women have, the shopping sprees. Pretty expensive and emotionally taxing.

A little bit of gender stereotyping here DA.

For example, household responsibilities are divided so women actually have to do less work over all.

I can't help but think that it would be better for the woman to divide household responsibilities with her husband and children!

But so long as the guy doesn't play favorites and the family only includes as many wives as can be loved (maybe only two).

I think for most men, "playing favourites" would be inevitable.

Also, it seems that nature has kind of supported this concept. The menstrual cycles of women living in close quarters all quickly adjust to a common time. This seems to favor procreation in that the man is able to avoid non-stop PMS; he only has to worry about a few days each month. The common cycle also means that the women will be fertile at the same time, thus creating an atmosphere of...erm..excitement, thus encouraging intercourse.

I think if nature was supporting the idea, there would be significantly more girl babies than boy babies born and women's menstrual cycles would not synchronise. In fact human sexuality argues that monogamy is more natural; sex when not fertile is unusual and this can be seen as increasing bonding between sexual partners. I am not being idealistic here - adultery is natural too.

Secondly, the gene pool of humanity is changed for the better because the most capable men will be the ones able to take in multiple wives. The genetically inferior men are left unable to procreate and pass along their deficiencies.

Capable in this context only means capable of attracting multiple mates. I don't think this necessarily means better citizens. Also, don't forget the women carry genes and selection pressures for them is reduced in this system.
