FYI: Every society faces the difficult task of providing support for older people who are no longer working. In an earlier era, retirees lived with their adult children, providing child care and helping around the house. But those days are largely gone. Retirees and their adult children alike prefer living independently.
In a rational economic world, individuals would save during their working years, accumulating enough to purchase an annuity that finances a comfortable standard of living when they retire. But that is not what most people do, either because of their shortsightedness or because of the incentives created by government social-security programs.
