Generally, we agree that making sacrifices for the good of others is good morals. High rates of having children out of wedlock, and divorce, are caused in significant part by unwillingness to make the sacrifices that would ensure a stable, financially secure home for children. These days, it’s often because men lack morals and are unwilling to sacrifice personal freedom to enter and stay in marriages, to the detriment of children.

Divorce has tremendous negative consequences on children. The childhood poverty rate for children of married couples is under 7%. For the children of single parents it’s over 37%. A Stanford study found that children of divorce die five years earlier than children of intact families.
