Cohen and Zysman argued that manufactures were related to services like “the crop duster to the cotton fields, the ketchup maker to the tomato patch,” and that if you “[o]ffshore the tomato farm…you close or offshore the ketchup plant….No two ways about it.”
Cohen et John Zysman disent que la production manufacturière est liée aux services comme "l'avion d'épandage agricole aux champs de coton, le fabricant de ketchup à la plantation de tomate…" et que "si la plantation de tomates ferme ou se délocalise, l'usine de ketchup doit aussi fermer ou se délocaliser".
