Les produits dérivés sont à l'économie réelle ce que l'usure est à l'épargne et à la production. Comme le grand poète Ezra Pound nous l’a enseigné dans son poème: «Par usura n'ont les hommes maison de pierre saine, blocs lisses finement taillés pour que la frise couvre leur surface.
Derivatives are to the real economy as usury is to savings and the productive economy, as a great American poet, Ezra Pound, taught us in his canto: ‘With usura hath no man a house of good stone each block cut smooth and well fitting that design might cover their face, with usura seeth no man Gonzaga, no picture is made to endure nor to live with but it is made to sell and sell quickly, sin against nature.
