The family is a natural society with its own nature and integrity. Because of the natural reality of the family, we have certain obligations. If you are a husband or a wife, you have certain duties to your spouse. If you are a parent, you have certain duties to your children, regardless of whether or not you ever chose them. And children, not Social Security administrators, have duties to their parents, especially as they age. It is the natural reality of father and child, mother and child, that creates the relationship of authority and responsibility.
This places limits on what the government can do. The government is not free to recreate the family. The government is not free to usurp the authority of parents over the education of their children or adult children over the care of their elderly parents.
