I live in Arizona. There is a town that practices polygamy in very northern Arizona.

They are not legally married to the second, third, fourth, etc wives. They are "spiritual marriages." So the extra wives are not legally married and receive welfare benefits for their children. So they are exercising their religious beliefs at the expense of taxpayers.

Many of these extra wives are young teenagers (as young as 13 or 14) who have no say in whether they marry 40 year-old men. They are given as wives, regardless of their wishes.
