Context

““has his wages advanced to him by his master, he in reality costs him no expense, the value of these wages being generally reserved, together with a profit, in the improved value of the subject upon which his labour is bestowed.” (A. Smith, l. c., Book II. ch. III, p. 311.) 6 “This is a remarkably peculiar property of productive labour. Whatever is productively consumed is capital and it becomes capital by consumption.” (James Mill, l. c., p. 242.) James Mill, however, never got on the track of this “remarkably peculiar property.” 7 “It is true indeed, that the first introducing a manufacture employs many poor, but they cease not to be so, and the continuance of it makes many.”” source
