Nuclear Family

The Necessity of the Nuclear Family

By Elise DeYoung

Many say we are living in an age of progression. However, our modern age could accurately be titled “The Age of Regression.” Morally, socially, economically, globally, educationally—we have allowed the poison of individualism and secularism to sweep across our nation, removing tradition in its wake.

Possibly the most invaluable tradition that the Left has banished from its self-proclaimed “progressive utopia” is the family—specifically, the nuclear family. This has resulted in extreme social consequences because the family is the fundamental building block of society.

How did we get here?

George Murdock

George Murdock reached this exact conclusion in his book, Social Structures, published in 1949. His work studied hundreds of diverse civilizations across time in order to understand the “science of human behavior.” Even today, it is considered one of the most comprehensive works on the subject.

The first chapter deals specifically with the nuclear family, which he defines as “a married man and woman with their offspring.” In it, Murdock observes that “the nuclear family is a universal human social grouping… it exists as a distinct and strongly functional group in every known society.” He concluded that after examining over 250 cultures, no other social structure could replace the nuclear family on a fundamental level. 

How does Murdock measure the success and strength of this family structure? He evaluates the four vital functions of the nuclear family: the sexual, economic, reproductive, and educational functions.

The Sexual Function

The sexual function, fulfilled through the sexual union (marriage) of spouses, aligns sexual desire with morality and decreases cultural perversion.

Regrettably, we now live in a deleterious society that shames all sexual restraint and celebrates sexual promiscuity. Murdock warned against forsaking the sexual function, saying, “Sex cannot safely be left without restraints.”

Clearly, we are suffering from the consequences of disregarding this warning. Whether it be the entertainment industry, sex education for minors, pornography and prostitution, immodesty, reproductive control, LGBTQ+, or the internet, sex is being promoted without restraint and consequences, completely divorced from marriage.

What were the results?

  • In 2015, the Supreme Court enshrined the contradiction “gay marriage” into law with Obergefell vs Hodges.[1]
  • 60–71% of children have sex before graduating high school.[2]
  • 15.2% of young adults aged 18 to 24 identify as LGBTQ, a stark contrast to older generations who rank below 5%.[3]
  • In 2017, OnlyFans had 100,000 users, and in 2021, the number skyrocketed to 187.9 million users.[4]
  • 45% of American adults are married, down from 50% in 2015.[5]

This is an extreme problem, not only for the poor people who have fallen prey to these statistics but also for the overall health and sustainability of our society. We have ostracized sexual restraint through marriage, and instead, invited both sexual perversion and promiscuity to rule our minds, lives, souls, and civilization.

The Economic Function

The economic function establishes the division of labor and ensures that each family member is fiscally cared for. Murdock describes the division of labor as follows: the husband takes care of the wife, the wife takes care of the husband, and together, they take care of their children until they are old enough to take care of the parents. This charitable model creates a “gridlock of caretaking” where each member’s needs are accounted for.

This gridlock does not ensure that the nuclear family will be wealthy. However, the statistics prove that it is more likely for a nuclear family to be better off fiscally compared to single-parent homes. The Office of Juvenile Justice and Delinquency Prevention (OJJDP) found, “Children in single-parent families are more likely to live in poverty.” In 2021, 9.5% of children living with two parents lived below the poverty level, compared to 31.7% of children living with a single parent.

However, if American leaders, laws, and voters are genuinely interested in solving poverty or helping young people reach success, they must return to promoting and protecting the nuclear family.

Let me clarify that these general findings are not meant to discourage single mothers or fathers in America. However, if American leaders, laws, and voters are genuinely interested in solving poverty or helping young people reach success, they must return to promoting and protecting the nuclear family.

Melissa Kearney said it well in Time Magazine, “The economic data is clear: to make our nation’s economy stronger for all men, women and children, marriage and family structure must be acknowledged as a driving force of economic well-being. And we must promote positive, shame-free ways of changing our social and economic views on marriage to make improvements that help the nation now and, in the decades, ahead.”[6]

The Reproductive Function

The reproductive function replenishes society by procreation.

It is no secret that for a society to survive, let alone flourish, the members of that society must make more babies. This is arguably the most important aspect of the nuclear family, because it’s the only family structure that can naturally result in the reproduction of children. But, what happens when we abandon this model?

Having children is not only a matter of their own flourishing or society’s; this is about survival.

The immediate effect is birth rates plummet. The birth rate in America has dramatically decreased from 14.3 births per 1,000 people in 2007 to 11.1 in 2021.[7] This is partially due to the decreasing pregnancy rates which, in 2017, reached an all-time low among women aged 24 and younger. This decline has been consistent since the 1980s.[8] Furthermore, since the 1970’s, millions of babies have been murdered in the womb through abortion. In 2021 alone, 626,000 unborn babies were killed.[9]

These two factors result in a rapidly declining birth rate. These numbers are clearly not sustainable for any civilization. Once again, the solution is clear. We must stop killing babies, and encourage young people to get married and have a lot of children. This is not only a matter of their own flourishing or society’s; this is about survival.

The Educational Function

The educational function, fulfilled when parents teach children values and ideals, will result in their flourishing.

We’ve established that the nuclear family provides children with the best fiscal position in society. Not only this, but children within the traditional family structure statistically perform better educationally.

“A new study finds that that by the age of 24, individuals who live in single-parent families as teens received fewer years of schooling and are less likely to attain a bachelor’s degree than those from two-parent families.”[10]

This fact is undeniable in our current age. However, while graduating high school is invaluable in society, it is not the main purpose of the educational function of the family. This is because graduating with a piece of paper does not equate to a good and true view of the world.

This is clear in our current age with the poison of progressive ideology seeping into our schools and corrupting the minds of our youth. It not only leaves destructive effects on the children, but it also threatens to derail our society at large.

Because of its ties to tradition and reality, the nuclear family is the family model best equipped to teach children ideas that will help them flourish in society. The values of marriage, love, charity, hard work, and child-rearing—among many others—are all fundamental to the four functions of the nuclear family.

The Necessity of the Nuclear Family

“In the nuclear family or its constituent relationships, we thus see assembled four functions fundamental to human social life—the sexual, the economic, the reproductive, and the educational. Without provision for the first and third, society would become extinct; for the second, life itself would cease; for the fourth, culture would come to an end. The immense social utility of the nuclear family and the basic reason for its universality thus begin to emerge in strong relief.”

The nuclear family is the fundamental building block of society. It is not only essential for our society’s survival, but is also the best solution to the problems of sexual promiscuity, economic collapse, declining birth rates, and other harmful ideas permeating our current climate.

Murdock said, “No society, in short, has succeeded in finding an adequate substitute for the nuclear family.” I suggest that we not even try.
