welfare *Libertarianism
is not a theory of welfare in the sense of quality of life. It is, however,
compatible in practice with preference *utilitarianism, which definitely is a theory of
welfare. However, this is an unusual theory of welfare in that what we prefer
need not relate to how we feel when it is achieved or even to ourselves at all.
But if people regard themselves as being better off to the extent that they get
what they spontaneously want (i.e., without *proactive imposition),
then this seems to be the conception of welfare that they would choose for
themselves (or choose above ‘welfare’, for those essentialists who deny that
this can be a conception of welfare). And *liberty and the *free
market give us more of what we individually want. *Politics involves
politicians attempting to give us more of what they think we ought to want, and
they often even fail at that. See *consequentialism;
