"The prohibiting duties we lay on all articles of foreign manufacture which prudence requires us to establish at home, with the patriotic determination of every good citizen to use no foreign article which can be made within ourselves without regard to difference of price, secures us against a relapse into foreign dependency."
--Thomas Jefferson to Jean Baptiste Say, 1815.
