Marriage is the most romantic of institutions, but when a person has more than one spouse, it can lead to many problems, Rabbi Shmuley says. He discusses how polygamy has a negative effect on society.

Marriage is the very foundation of society because of its civilizing influences, Rabbi Shmuley says. "Marriage takes a man and a woman who are strangers to each other, orchestrates them together into inseparable flesh and lends children a stable and secure environment within which to be raised," Rabbi Shmuley says.

But when husbands have multiple wives, the wife no longer feels adequate enough because she alone does not satisfy him. Instead, she is forced to compete for her husband's affections. Rabbi Shmuley says polygamy also disrupts the friendships that are formed among women, who are often vying to win the attention of the same man.

In addition, polygamy negatively affects children, Rabbi Shmuley says. "[It] offers children a model not of security but of rivalry, not of confidence but of permanent insecurity, as the members of a single household compete to be favorites," he says. "It is a toxic environment in which men are kings and women are courtiers."
