Whatever quibbles you may have with the details of his
arguments, don't you think that Sowell made it difficult to
offer such blunt assessments of the "classical" economists?
And even if we put aside say Sismondi and Malthus.  E.g.,

        it may very well occur, that there may be, at some
        given time, a very general inclination to sell with
        as little delay as possible, accompanied with an
        equally general inclination to defer all purchases
        as long as possible.
        -- J.S. Mill, as quoted by Sowell (CER, p.49)
