For an argument against the rationality of the Rawlsian project 
on economic grounds, see Israel Kirzner, _Discovery, Capitalism, and 
Distributive Justice_.  In Kirnzer's view it does matter to the 
persuasive failure of the Rawlsian project that it is grounded in a 
unjustifiable picture of resource use coordination in an extended society.
