They are group production and technology intensive. One Boeing passenger plane can rush to Wenzhou to make 400 million shirts or leather shoes. It takes three months to build a Boeing passenger jet. It will take several years to make 400 million of our leather shoes, and we may not be able to sell them all.

In addition to being valuable in themselves, Boeing passenger planes also have high added value after they are sold. A large amount of money can be made from airport renovation, communications, navigation, personnel training, spare parts, etc. Once your leather shoes and shirts are sold and used up, they have no added value other than being thrown away in the trash. Haha

A Raptor fighter is more expensive than a Boeing 747, costing 380 million US dollars. Even more powerful.

A memory stick on a Raptor fighter fire control computer costs 2 million US dollars each. Even if you build 40 Audis, it won’t be enough. A memory stick is just a circuit board smaller than a palm.
