In fact, polygamy makes more sense than monogamy

LOL!!

Of course it does...in SOME cultures!!

If the man is a farmer and needs a large/cheap supply of labor, there is nothing like a large family that can be had from 5 or 8 wives.

Polygamy may also be a way for wealthy people to counteract the effects of poor health/sanitation in some communities by restocking the gene pool with more people if there is high disease and a low birth survival rate. If a poor man is trying to be a polygamist, he will likely be peeing against the wind since he will be unlikely to provide for all of his offspring, dooming them to an early grave.

In the modern western world polygamy doesn't make as much sense.
