Use-Value, Economics, Morality

As decisive in Demand, Use-Value is a significant factor in the determination of Exchange-Value.  But, Use-Evaluation presupposes some End to which its object is a means.  In turn, the value of an End is in the purview, exclusively, perhaps of Morality.  So, even sophisticated quantitative, i. e. monetary, representation of Use-Value cannot completely immunize an Economic system from Moral scrutiny.
