U.S. helped to industrialize Germany after the Second World War, and also helped to industrialize all countries with borders on communism, thus also the Asian giant was born, with China, South Korea, etc.. That is, it is possible that the export growth has helped the United States to grow as well, which is logical. But more than pure profit law, the only law that exists today in the economy; at that time was what won an ideological prejudice against countries that could export communism. This in turn helped to grow in Europe and the United States did not mind helping with a Marshall Plan. Now it’s different, now because there is no Cold War, and the struggle against communism. Countries are linked or tied only by economic laws purest interest, profit. It is very difficult now with this competition between nations to establish a cooperative solution. Europe is in ruins, apparently because debt has been flooded, but the contraction of Europe means a closed market and close the possibility of exporting for other countries.
