Also, since the male/female ratio is about 1:1, does that mean that not all men can have a happy afterlife, since there just aren't enough women to go around?

That's where the suicide bombers come in -- you have to give the surplus males a chance at heaven.

Clearly, that's the reason why polygamy fails in the long run. It produces an unhappy and violent culture where half your labor force is wasted and much of the other half runs around horny and looking for someone to take it out on.

Ah, but the goal of polygamy is about having lots of kids. It's good for those seeking cheap (free) labor (like on farms).

In some countries that still permit polygamy, there are also mistresses and even sex slaves. Polygamy isn't about finding another "perfect wife" or having lots of sex.
