There was once a time in American history where many married couples lived comfortably with one income source. Typically, the husband would work full-time and his salary would be sufficient to pay for all of the couple's needs. In that scenario, the wife would usually remain at home throughout the day and take care of the children and other household duties. Divorce under those circumstances usually proved disastrous for stay-at-home moms with few marketable professional skills.
The role that parents play in the development of their children's lives is extremely important. Research undertaken on behalf of the Department of Health and Human Services indicates that the absence of a father in a child's life can actually have negative consequences for the child's cognitive ability and educational achievements.
