government to force people to act against their own immediate interests in order to promote a supposedly general interest. - Milton Friedman

Economic freedom is an essential requisite for political freedom. By enabling people to cooperate with one another without coercion or central direction, it reduces the area over which political power is exercised. In addition, by dispersing power, the free market provides an offset to whatever concentration of political power may arise.

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.

When everybody owns something, nobody owns it, and nobody has a direct interest in maintaining or improving its condition. That is why buildings in the Soviet Union — like public housing in the United States — look decrepit within a year or two of their construction.
