This paper examines contemporary attitudes toward marriage in the United States, arguing that the traditional assumption of marriage as a universal and necessary lifestyle for all adults may no longer hold. Drawing on sociological and psychological research, the paper surveys the decline of economic necessity as a driver of marriage, the prevalence of marital infidelity and divorce, the predictable erosion of sexual satisfaction within long-term marriages, and shifting cultural attitudes toward parenthood. Together, these factors suggest that many modern adults are critically reassessing whether lifelong marital commitment aligns with contemporary social realities and personal fulfillment.
The institution of marriage has been a fundamental part of human culture throughout recorded history. In modern times, however, marriage may no longer be as necessary — especially for individuals who have no desire to procreate. Combined with evidence that sexual infidelity in marriage is widespread (Barash & Lipton, 2001) and that more than half of all American marriages end in divorce (Branden, 2003; Roberts, 2007), these developments suggest that the cultural assumption that marriage is the most natural lifestyle for all adults may no longer be valid.
Prior to the middle of the 20th century, marriage was a practical necessity simply because the responsibilities of earning a living and maintaining a home were tremendously difficult for single individuals without the help of a spouse (Branden, 2003). Nowadays, it is no longer rare for single adults to support themselves comfortably — a situation that, especially for women, was extremely rare as recently as several generations ago (Branden, 2003). The fact that economic necessity is no longer as strong a motivation for marriage has allowed many adults to postpone marriage — sometimes indefinitely — for various reasons, including the hope of finding the ideal life partner.
According to sociologists, marital infidelity is very widespread, with as many as seventy percent of married men and fifty percent of married women engaging in sexual infidelity at some point in their marriages (Barash & Lipton, 2001). Furthermore, psychologists report that both general satisfaction and sexual interest within marriage decline substantially and at very predictable intervals in most traditional marriages (Angier, 2007; Roberts, 2007). The average length of marriage in the United States is less than eight years (Branden, 2003; Roberts, 2007) — a striking figure given that marriage is supposed to be a lifetime commitment.
As a result, many adults question the need for a lifetime commitment to another person, particularly since long-term sexual fidelity and happiness in marriage are apparently more the exception than the rule (Branden, 2003). Research on monogamy and pair bonding across species further complicates the assumption that exclusive lifetime partnership is either natural or inevitable for human beings.
"Many adults reject procreation as a necessary goal"
Marriage has traditionally been a fundamental staple of human cultures, but in contemporary times, many American adults may be reconsidering its necessity. Changing attitudes about the assumption that parenthood is a responsibility to which all adults must aspire is one significant factor. The fact that a marital union is no longer an economic necessity — combined with the reduced influence of religion — is also partially responsible, as are perceptions of the reality of long-term sexual fidelity in marriage. Together, these forces suggest that the universal ideal of marriage as the natural endpoint for all adults deserves ongoing critical scrutiny.
