13-1a3a2a The difference is implied in any exchange and division of labor

“Praxeologically, the very fact of exchange and the division of labor implies that it must be more productive for all concerned than isolated, autistic labor.” – Murray Rothbard

“One may as well consider these two facts as one and the same fact, namely, the manifoldness of nature which makes the universe a complex of infinite varieties. If the earth’s surface were such that the physical conditions of production were the same at every point and if one man were … equal to all other men … division of labor would not offer any advantages for acting man.” – Ludwig von Mises
