"Although money, and so monetary calculation, will disappear in socialism this does not mean that there will no longer be any need to make choices, evaluations and calculations...Wealth will be produced and distributed in its natural form of useful things, of objects that can serve to satisfy some human need or other. Not being produced for sale on a market, items of wealth will not acquire an exchange-value in addition to their use-value. In socialism their value, in the normal non-economic sense of the word, will not be their selling price nor the time needed to produce them but their usefulness. It is for this that they will be appreciated, evaluated, wanted. . . and produced" (Socialism and Calculation).
