I don't believe the government should support any social program. Let those who are concerned about a particular issue start a charity or foundation for that issue.
I do believe in a moral fabric, though. Without a moral map, the society falls into chaos. Society becomes a bed of filth and disease.
The moral foundation supports the Constitution. Without that moral base, i.e., the concept of right and wrong, the Constitution becomes a document that depends on the meaning of the word "is", and is no longer relevant. It would be rewritten upon the whim of a judge (and we're just about to that point right now).
