The problem as I see it is this:
OK so we used to be the factory to the world we made bulldozers airplanes etc.
The foreign country would trade what they have ie bananas or coffee or etc etc
The question now becomes
How many bananas do they have to sell to get a Boeing 747 or Cat D 9?
I remember Boeing having a bunch of Izuzu trucks. Why? Well dont the Japanese have to trade something to get an airplane?
I dont have the answer to this but I sure wonder about the questions.
