"Smith chapter 5-talked the language of a labor theory of value-labor a   
determinant of value-that labor is the essence of value-things have   
value because of pain-pain the basis of desert.  Genesis 3:16 ?  In the   
sweat of thy face shall thou eat bread-a fallacy in economics."  
  
Edwin Cannan's first annotation to chapter 5 of the Wealth of Nations   
reads, "Labour is the real measure of exchangeable value," p. 34 of the   
1976 University of Chicago Press edition.  At the end of the first   
paragraph of that chapter, Smith himself writes: "Labour, therefore, is   
the real measure of the exchangeable value of all commodities."  
  
Luigi Pasinetti (1960), Samuel Hollander (1973, 1987), Will Mason   
(1982), and some others have reiterated the point that Smith did not   
argue a labor theory of value, but a *measure* of value.  I wonder when   
the fallacious attribution of what Smith did not say will end.
