Assuming that the technical questions have answers, do we want a system in which the government divests itself of responsibility for the human needs that gave rise to the welfare state in the first place? I think the reasons for answering "yes" go far beyond the Plan's effects on poverty, retirement and health care. Those issues affect comparatively small minorities of the population. The more profound problem facing the world's most advanced societies is how their peoples are to live meaningful lives in an age of plenty and security.

Throughout history until a few decades ago, the meaning of life for almost everyone was linked to the challenge of simple survival. Staying alive required being a contributing part of a community. Staying alive required forming a family and having children to care for you in your old age. The knowledge that sudden death could happen at any moment required attention to spiritual issues. Doing all those things provided deep satisfactions that went beyond survival.

Life in an age of plenty and security requires none of those things. For the great majority of people living in advanced societies, it is easily possible to go through life accompanied by social companions and serial sex partners, having a good time, and dying in old age with no reason to think that one has done anything significant.

If you believe that's all there is--that the purpose of life is to while away the time as pleasantly as possible--then it is reasonable to think that the purpose of government should be to enable people to do so with as little effort as possible. But if you agree with me that to live a human life can have transcendental meaning, then we need to think about how human existence acquires weight and consequence.

For many readers of The Wall Street Journal, the focus of that search for meaning is bound up with vocation--for some, the quest to be rich and famous; for others, the quest to excel in a vocation one loves. But it is an option open to only to a lucky minority. For most people--including many older people who in their youths focused on vocation--life acquires meaning through the stuff of life: the elemental events associated with birth, death, growing up, raising children, paying the rent, dealing with adversity, comforting the bereaved, celebrating success, applauding the good and condemning the bad; coping with life as it exists around us in all its richness. The chief defect of the welfare state from this perspective is not that it is ineffectual in making good on its promises (though it is), nor even that it often exacerbates the very problems it is supposed to solve (though it does). The welfare state is pernicious ultimately because it drains too much of the life from life.
