" Printing dollars at home means higher inflation in China, higher food prices in Egypt and stock bubbles in Brazil. Printing money means that U.S. debt is devalued so foreign creditors get paid back in cheaper dollars. The devaluation means higher unemployment in developing economies as their exports become more expensive for Americans. The resulting inflation also means higher prices for inputs needed in developing economies like copper, corn, oil and wheat. Foreign countries have begun to fight back against U.S.-caused inflation through subsidies, tariffs and capital controls; the currency war is expanding fast. "
