"Cost the limit of price" was a maxim coined by Josiah Warren, indicating a (prescriptive) version of the labor theory of value. Warren maintained that the just compensation for labor (or for its product) could only be an equivalent amount of labor (or a product embodying an equivalent amount).[1] Thus, profit, rent, and interest were considered unjust economic arrangements. As Samuel Edward Konkin III put it, "The labor theory of value recognizes no distinction between profit and plunder."[2]
^ abIn Equitable Commerce, Warren writes, "If a priest is required to get a soul out of purgatory, he sets his price according to the value which the relatives set upon his prayers, instead of their cost to the priest. This, again, is cannibalism. The same amount of labor equally disagreeable, with equal wear and tear, performed by his customers, would be a just remuneration
^Smith writes: "The real price of every thing, what every thing really costs to the man who wants to acquire it, is the toil and trouble of acquiring it." Note, also, the sense of "labor" meaning "suffering."
