Back in the day, polygamy in the Mormon church was not for everyone. Only those in leadership positions. Generally those with some money, as supporting a large family required bank. Usually, getting a leadership position meant you had money (as it does today). I said usually. Easy, there.
I come from polygamists. My great-great grandfather had 7 wives. One of them left him. That would be my great-great grandmother. She paid for it. He left their offspring $1 each, so they couldn’t legally contest the will. This was over a hundred years ago. You wanna talk about punk rock women?
