From African village model to the nuclear family is a massive step, made possible by the nation state. Arguably this impoverishes community/extended family life. The most extreme form can regularly be read in the news: somebody found dead in their home, undetected for weeks or months.
But not even that is enough. Even within the scope of the nuclear family are we further individualizing. Each partner in the couple is to be fully economically independent from the other. Note that I'm not suggesting any traditional angle here, I'm purely talking about individualism in general. Even within our very own family, we no longer dare to rely on each other, to be dependent on each other.
If I were to pick a cliche busy urban family, they have very few shared moments. They may not even eat together. They relax on their own individual device, often in separate rooms. And we outsource care for both our young and the old.
We drifted far from our roots.
