I never understood how plural marriage was supposed to work. If practiced widely there wouldn't be enough females to go around.

Kinda like in China where they have a girl shortage for an entirely different reason.

One's enough for me. Who needs more than one mother-in-law anyway?

You are exactly correct. There aren't enough females to go around, so "lost boys"
are unceremoniously dumped by polygamous Mormon sects. You can read more
about this terrible practice here.

It wasn’t ‘open season’ for any guy to get as many as he wanted. A man would have to be asked by the church to take a plural wife before the church would marry him to another woman, so only a small percentage of people actually were practicing it.
