What are the most important industries of the United States of America?

Answer 1

Obvoiusly a superpower whether it be the USA, China, Russia, Japan etc MUST have an industrial base and that is what worries me about the United States. Our country has lost in almost every industry group there is and we have turned into a "service" economy. This will not work for a superpower.

The US does lead the world in a few industries. Weapons technology, aerospace and medical sciences are still led by the US. Computer technology, which is the latest American loss is actually a tie with India, China, Japan and other Asian nations.

I lost my career in the Airline industry so I have an avid interest in commercial aviation. The US is seriously challenged by the Europeans (EADS/Airbus) and there are a few other nations that are leaders in commercial aircraft (Canada- Bombairdier/ Brazil- Embraear/ China- CANC and Japan- Mitsubishi Heavy Industries) The US company Boeing is the worlds #2 commercial aircraft maker after losing to Airbus last year. Like Airbus, Boeing contracts worldwide for subsystems for it's aircraft but still is an American company and American technology ruled. Airbus uses a lot of American systems. The military aerospace area is dominated by the United States along with weapons platforms other than airborne and we cannot lose in this field.

Answer 2

In economic terms, probably the Petroleum (Oil into products) industry. From Oil, we get plastics, fuel, heat, power and many othr benefits. Without oil, the world would effectively stop.

Answer 3

Food, nutrition
