Demand, Wish, Need

While a Wish is conscious, and is for an object that may not satisfy an organic lack, a Need is an organic necessity, even if not consciously entertained.  Now, those differences are morally significant to both Aristotle and Mill, i. e. expressed in the former's distinction between apparent and actual Good, and in the latter's between lower and higher pleasures.  In contrast, the standard Economic concept of Demand does not distinguish them, and is usually taken as equivalent to Wish.  Accordingly, any Economic system that takes that concept at face value is, at minimum, amoral, and insofar as a program takes it as sacrosanct, e. g. as a factor in the promotion of Wealth, or in dogmatic laissez-faire Capitalism, it is arguably immoral.
