Why is American technology so awesome? Whether it's electronics, avionics or military field?

Americans are actually not smart. The smartest people in the world should be Jews and Chinese. There are many factors that contribute to the technological prowess of the United States. First, the United States was not attacked in the two world wars, and its domestic industrial base was well preserved. The established powers such as Britain, France and Germany declined because of the destruction of domestic industries in the two world wars. The first world war put the United States on an equal footing with the European powers, and the second world war left the United States behind the European powers. Second, talents, because the main battlefields of the two world wars were in Europe and Asia, and the United States was safe and sound, which made a large number of refugees flood into the United States, and there were many scientists, the most famous of whom was Einstein's. Because of Hitler's persecution of Jews in the Second World War and the Japanese destruction of China, a large number of Jews and Chinese took refuge in the United States, which brought a large number of labor necessary for industrial development to the United States, and at the same time, Jews and Chinese had a large number of talents in the United States. Third, capital, the United States made a fortune in the two world wars and accumulated a lot of capital for the development of capitalism. However, European powers were heavily in debt after the two world wars and relied on the United States for post-war reconstruction, which once again widened the gap between Europe and the United States. Fourth, the military, as we all know, the Second World War was a period of rapid development of science and technology, and a large number of military technologies emerged, mainly thanks to the Germans. After entering Germany, the US military brought many advanced weapons from Germany back to the United States. Many weapons in the famous Aberdeen proving ground came from the United States, and Americans were more advanced in military thinking. They often invented weapons on the battlefield, such as the helicopter gunship, which is now known to all. In fact, the US military was on the battlefield in Vietnam. Fifth, society, because the United States has established a capitalist society without experiencing feudal society, the United States is the country with the best development of capitalism. On the one hand, it has perfectly absorbed Montesquieu's separation of powers, on the other hand, it has well realized the theory of social contract. It can be said that Americans have never known what kingship is and what is superior. A reasonable social system makes American government institutions more reasonable and social contradictions relatively relaxed (I won't say racial contradictions, everyone understands) Sixth, leaders, looking at American history, we will find a wonderful thing, that is, whenever the United States encounters a crisis, there will always be leaders who step forward, not only to lift the crisis, but also to make the American economy go up a storey still higher. This is very remarkable, just like Roosevelt. You should know that in Europe at the same time, there was a Hitler in Germany and a Stalin in the Soviet Union. Seventh, it is the population and territory of the United States. I have to say that the ratio of population and territory of the United States is really perfect, which is different from China's large population and small population. It is also different from Russia's vast territory and sparsely populated. The United States has the fourth territory in the world, and the third population in the world. The land is not tight, and the population is not small, which has created developed farms in the United States. Less than 6 million farmers support 3 million Americans. I am afraid that China cannot do this. The United States. Finally, resources, the United States is very rich in resources, which can basically be said to have everything. This is the advantage of the United States compared with Japan. The United States is not only rich in resources and reserves, but also has a very high per capita share. The American government and people have a very strong sense of protection. While China is still mining a large number of rare earths destructively, the United States has banned domestic rare earth mining for a long time. There are quite a few rare earth reserves in the United States, but they only import them, not mining them at home. The China government has just started. Although I am very disgusted with the United States as a China person, I think no country in the world can deny the strength of the United States.
