If i'm understanding the question correctly, then everyone else hasn't answered the question. Considering how we have only had one economic collapse (The Great Depression) the other downfalls were only downfalls, I believe you are asking how we went from being the country that the Great Depression hit the hardest to being the Supreme World Power that we are today.
The Great Depression hit every world power for the exception of U.S.S.R. It hit England and France, but thanks to their colonies, they were able to get by with much more ease. The United States and Germany weren't so lucky since they had no colonies. The Great Depression hit the two countries hard. By 1933, FDR was in power in the United States. Hitler was in power in Germany. Both had solutions to recovering from the Great Depression and never having one again. Roosevelt proposed a series of "New Deals" which changed the government, economic, and social structure of the United States to better the poor and working classes. Hitler believed the only real solution is to make his nation huge. He therefore attacked little countries first and then moved onto the larger countries of France, England, and Russia.
Just before WWII broke out in 1939, all of the powers that had suffered from the Great Depression had pretty much recovered enough to regain their status as world leaders. The world powers were U.S.A., U.S.S.R., England, France, Italy, Germany, and Japan. As WWII broke out, all that would change dramatically.
Germany devistated all the countries it took over. The French Economy had collapsed. England, because of the money spent on the War and the damage done by Battle OF Britain and other German Bombings of Britain, also lost its status as a world power and its economy was barely functioning enough to keep on fighting. Italy was being overrun by Allied Forces by 1943 and it had no economy left. The War on the Pacific Front had enabled Japan to expand dramatically, but at the cost of losing its entire naval and air fleets and the Americans right on their backs. The U.S.S.R. was one of two main countries that was producing the supplies for the war and therefore was able to keep its economy in good strength even after losing 20 million people in the War. U.S.A. was the other major supplier of the Allied Forces. Its economy was booming thanks to the War since it was now the largest military supplier in the world and one of only two suppliers in the world after the War. By the time WWII ended, both Germany and Japan had suffered greatly and the Allied Forces had crushed the two countries. Both economies had collapsed upon the weight of the Allied Forces.
This left only two countries with any world power: U.S.A. and the U.S.S.R. The U.S.S.R. only aided the communist countries in Europe (i.e. countries under U.S.S.R. control) and therefore the U.S.A. was the only country in the world that could supply the war-stricken Western Europe and Asia. As a result, every capitalist nation on Earth was buying almost entirely from the U.S.A. Thus, the U.S. economy boomed and its stature as the Supreme World Power grew and grew. At the same time, U.S.S.R. was also in an economic boom since it was also supplying countries such as China, North Korea, and Vietnam. the U.S.S.R. was also seeing its status as a Supreme World Power Grow.
It took twenty years before any nation to come close to the power that U.S.A. and U.S.S.R. had. During that time, the two countries were still booming and power was growing. But also during that time was the Cold War which basically was a bloodless dissagreement between the Capitalist and Communist nations. By the early 1990's, the Cold War had ended with the U.S.S.R. collapsing. Thus, there was only one Supreme World Power left standing: U.S.A. (though there were now world powers such as England, Canada, Australia, China, Japan, Germany and a few other Western European nations and Asian nations). United States had become the undisputed Top Dog of the 1990's and even today.
However, China is the world's fastest growing economy and its power is growing while our own power is shrinking thanks to our poor reputation among the other nations as a result of the last few wars U.S.A. started. It seems that within 50-100 years (if that) China will replace the U.S.A. as the Supreme World Power and United States will become its lapdog or "big brother."
