Demand, Need, Morality

As has been previously discussed, the standard concept of Demand does not distinguish between Wish and Need.  But, that contrast is not only that between frivolity and vital necessity.  It also expresses the depersonalization implicit in the terms of any generalized Economic model, Micro- or Macro-, especially qua quantified.  Thus, the Socialist formulation, 'each according to his need', restores such models to a Moral context.
