America: The Story of Us It is an amazing documentary. Why America developed into a superpower in less than 300 years? After watching this documentary, I have my own point of view. First, the geography advantage. America is far from Eurasia continent; the major battlefields of The Second World War are far away from the mainland of America, so the economy and infrastructure in America are not jeopardized during the war. Besides, Vast territory and sporadic native american tribes ruling on it mean it is very easy for the decedants of Mayflower to take over the power of sovereignty. Additionally, the Mississippi and Missouri rivers are north-south, different from Yangzi and Yellow rivers in China which are east-west. Different latitude means different resources, and Missouri and Mississippi are the best means of transportaion. Last but not least, America is a miracle land with vast amount of natural resources. Threre are limber in Michigan, coal in Colorado, crude oil in Texas, and gold in California. All raw materials to develop industry and mass production can be found in this country. What a sweet miracle given by god! Second and third reason is under production.
