I think it is only because capitalism has proved so enormously more efficient than alternative methods that it has survived at all. (...) I'm not sure capitalism is the right word.

As these remarks indicate, the Social Security program involves a transfer from the young to the old. To some extent such a transfer has occurred throughout history — the young supporting their parents, or other relatives, in old age. Indeed, in many poor countries with high infant death rates, like India, the desire to assure oneself of progeny who can provide support in old age is a major reason for high birth rates and large families. The difference between Social Security and earlier arrangements is that Social Security is compulsory and impersonal — earlier arrangements were voluntary and personal. Moral responsibility is an individual matter, not a social matter. Children helped their parents out of love or duty. They now contribute to the support of someone else’s parents out of compulsion and fear. The earlier transfers strengthened the bonds of the family; the compulsory transfers weaken them.
