The United States Constitution evidently calls for monetary arrangements with a strict metallic standard-gold, silver, or bimetallic. How were these provisions overturned so as to result in today's fiat-money arrangement with no trace of a metallic standard? A crucial step involved Supreme Court decisions after the Civil War with regard to the constitutionality of the fiat "greenbacks" issued during the war. The reasoning expounded by the Supreme Court in these decisions relied importantly on a failure to distinguish between monetary and fiscal policy provisions. Essentially the same failure has been present in much of the recent discussion concerning the financial crisis of 2007-09.
