The all-round advantages and capabilities of the United States' industries are very prominent, and no other country in the world can compare with them. Space industry (satellites, spacecraft, global positioning system), aviation industry, shipbuilding, biotechnology, modern agriculture, automobile industry, machinery manufacturing, nuclear industry, electronics industry, computer industry, network industry, financial industry, etc., all of which are directly connected to the military industry, and are even the foundation of the military industry. IT industry: high-tech industries represented by Silicon Valley, sales revenue accounts for a double-digit proportion of the US GDP. IBM, HP, Dell, Microsoft, Cisco, Google, Ebay, etc., each company is the first or second in the world in their respective professional fields, and is basically not affected by the financial crisis. Aerospace: Boeing, Lockheed Martin, Grumman, etc., are basically not affected by the financial crisis, and their overall competitiveness ranks first in the world. Military industry: There is some overlap with aerospace, but the scope is wider, and it is not affected by the financial crisis, because defense orders and research and development have not been reduced at present, and its overall competitiveness ranks first in the world. The United States' annual military expenditure exceeds 400 billion US dollars, which is more than all other major countries combined. Its military products are world-class, and the technical level of its main military equipment is half a generation to a generation ahead of military powers such as Russia, Europe, and Japan, or even more. Financial services: The financial services industry represented by Wall Street is the world's economic and financial center, affecting every economic nerve of the world. During the financial crisis, some companies such as investment banks, funds, and banks were affected to a certain extent, but the competitiveness of a few companies was enhanced due to the weakening of their opponents. In the field of investment banks, the relative competitiveness of the US financial industry may not have declined, or the degree of decline is not as much as estimated. The US financial industry continues to move forward in the adjustment, and its vitality is still strong. Agriculture: With its unique natural conditions and developed modern agricultural technology, the US's competitiveness is still the world's first. Moreover, as the negative impact of the catastrophic climate brought about by global warming on agricultural production becomes increasingly greater, the US's agricultural competitiveness will continue to increase. Cultural industry: The industry that generates the most foreign exchange for the United States is not the aircraft and automobile industries, but the cultural industry represented by Hollywood - American blockbusters and derivative products. The American culture spread by American blockbusters is even more valuable than the income generated, because it subtly guides people to look up to and envy the United States.
