Can Society In Ultra-West Nations Survive A Breakdown Of The Family Unit?

The nuclear family is the core unit of society in those new nations carved out by European migrants in territories over the seas previously occupied by indigenous tribes. The latter, like the traditional societies of Asia and Europe (or parts thereof), are composed of kin family units.
These migrants would, in the main, have left established nations in Europe or sundry kingdoms or principalities, for religious, economic or official policy reasons (eg. Britain's cultural cleansing of those deemed to be criminal, or otherwise undesirable).
The nation, as a territory-related people, is a socio-political construct (or artificially created entity), arising in Europe no more than five centuries ago. Presumably reflecting the schisms within Christianity, tribes of a coherent people, bonded by a shared religious belief, history, territory, language, other cultural traditions, and consanguinity demarcated the defining boundaries (both geographical and tribo-cultural) to ensure separation from non-congruent or competing tribes.
Purely as an aside, at its height, European colonialism extended the reality of nationhood outside Europe by establishing national borders. These boundaries created new nations, disregarding pre-existing kingdoms or ethnic enclaves, often dividing peoples, just to achieve a balance of power between the European nations. The resultant tribal wars (eg. between India and Pakistan) may, however, have offered economic opportunities to the neo-colonisers of the modern day.
Migrating multitudes mixed peoples from source countries in the new territories in a manner not evidenced before. Without extended family support, necessary self-sufficiency developed. The subsequent eventual development of ethno-religious conglomerates probably resulted in loosely-knit communities.
However, the American scholar Francis Fukuyama has recently written about the great disruption to US society. Could one wonder whether the killing of the indigenes and the despoliation of their cultures has left some kind of debilitating residue in the national psyche? Be rational, obey the law, and look after your self-interest: these were apparently posited as a guide to a life expressing personal initiative in a land of opportunity.
Whatever the relevance of the above, Fukuyama's analysis is shadowed by a casual but extended observation of Australian society.
In Australia, where individualism is somewhat leavened by state welfare, this author's experiences and acute observations over six decades lead him to the following conclusions. The family unit, the fulcrum of society, and the vehicle for the transmission of the youth of the nation to their future, has been fractured. In the absence, or a substantive denial, of available extended family, a breakdown of marriage or cohabitation of duration leaves children in a parlous situation. There is no kin back-up available.
Since up to 40% of marriages are reportedly at risk, and since many, many fathers are allegedly denied continuing close relationships, as dictated by nature, with their children, what happens to the psychological needs of the children in broken families? Only recently has there been any admission that the children are adversely affected. Earlier claims that there is no evidence of damage did not seem credible, when one considers the imperatives of nature.
Yet, only the career needs of mothers, and their success in balancing motherhood and work, fill the media reports. The extended periods spent in professional care by babies and little children, the denial of their right to nestle at length in the arms of the mothers and, when older, to ask a million questions about all those interesting things out there, and to talk about all that, is never the subject of interest in the media. Why not? Fortunately, in low-employment districts, the children are seen to be receiving the entitlements designed by nature.
Then, there is a perceivable diminution of mutual respect, the reported denial by many youngsters of personal responsibility to contribute to the operation of the family unit, the audible spoilt child in the shops, a reported increase in the number of single mothers, and the seemingly escalating exploitation of welfare (especially the disability pension) by able-bodied people.
Fukuyama identifies in his analytical book 'The Great Disruption' other evidence of social alienation (but in the USA). He instances mealtimes, now lacking the 'structured rituals' of yesteryear, when families ate together, with parents thereby enabled to offer information and counsel to their offspring and, reciprocally, for the latter to talk about matters of relevance to them. This reinforces the bonds of the family.
Fukuyama also instances the risks of blending separated part-families, and the deleterious effects of broken homes on school learning.
