Marriage is the foundational relationship for all of society. All other relationships in society stem from the father-mother relationship, and these other relationships thrive most if that father-mother relationship is simultaneously a close and a closed husband-wife relationship. Good marriages are the bedrock of strong societies, for they are the foundations of strong families. One can see this strength manifested at the national and state level, as indicated in other works of the authors, such as the Index of Family Belonging and Rejection and its relationship to various outcomes.
The findings herein demonstrate that in marriage are contained all the five basic institutions, all the basic tasks, of society: family, church, school, marketplace and government. These fundamental tasks, well done, in unity between father and mother, make for a very good marriage. Within a family built on such a marriage, the child gradually learns to value and perform these five fundamental tasks of every competent adult and of every functional society. Gradually he is mentored in them, often unconsciously. Gradually she learns that she is expected to act similarly. Eventually, he and she become more and more expert in performing all five tasks. In other words, they gradually grow in competence and are ready to strike out into society and, eventually, to build their own family. How they do that will depend much on what they experienced in growing up in their families of origin.
The future strength of our nation depends on good marriages to yield strong revenues, good health, low crime, high education, and high human capital. As the following enumeration shows, smart parents and smart societies pay attention to the state and strength of marriage.
