With some frugality, I think it's physically and economically possible. Imagine an America where grandparents (and great-grandparents if any) live with one of their children's family. Assuming an average of two children per grandparent, it will be half of the households will have 2 children, 2 parents, and 2 grandparents, and the other half the traditional nuclear family. The nursing home infrastructure will be much reduced because only the childless will live in them. It can reduce the liability on social security. This can be countered with tax cuts to children who are working to support their parents. Implement a law where elderly parents can sue their children for parental support, to cover cases where children do not care about their parents. A society that cherishes the dignity of dying at home surrounded by friends and family as opposed to enduring 3 months of humiliating treatment before dying violent death surrounded by nurses, will reduce healthcare costs. Grandparents will also reduce the labor requirement for childcare, and also provide guidance and teaching during times when parents are too busy working from day to night. In the case of widows and widowers, and single parents, grandparents can increase the chance a child grow up with a role model of their own gender. Being supported by adult children means even in the case when a 50 year old parent loses their job due to ageism, they will not be forced to live on their streets; With some frugality it should be possible for a pair of children to support their parents and grandparents living in the same home. These dynamics will reduce the pressure on the government budget, increase social capital, increase the sense of belonging, reduce the dependency for "a job" even when you're 50+, reduce the cost of housing by reducing demand, and by sharing furniture and other goods, reduce household expenditure. A 50 year old unemployed couple will be able to converse and socialise with their retired 75 year old parent(s) as a day-to-day activity. And when you're spending time with people, in a house with a family, with clean water, sufficient food, electricity and internet access, with regular social gatherings, can you really be said to be in "lonely poverty"? That said, all this is physically, economically possible today, but it is probably not politically or socially possible. It will take further decline before people finally realise it is what they've wanted all along.
