So now that we've demonstrated that there is a net benefit to the US when trade is balanced, let us continue and ask what it means when there are trade restrictions against US exports to a country while the US allows imports to that country.
To make things simple on ourselves, imagine that Japan refuses to allow any exports from the US while there are no trade barriers against Japanese exports. Now the situation is even better. The US gets Toyotas. What does Japan get? Small, green pieces of paper (which cost the US cents on the dollar to produce). Japan is free to keep them as long as they want. As long as the US has printing presses and trees it can continue to supply Japan with these pieces of paper, which for some reason the Japanese have chosen to accumulate. If the Japanese decide one day that they have no further need of these pieces of paper they are free to:
1) exchange them with the US (in order to import goods and services from the US) in which case we are back to the Iowa car crop
2) exchange them with somebody else for something, which is really none of our concern
3) exchange them with the US for assets in the US. Imagine, for example, that they buy a car factory in Tennessee. Now we have the best of both worlds. Construction workers, steel mills, concrete suppliers etc have discovered a way to turn buildings and machinery into Toyotas. However, instead of shipping these buildings out on barges the US gets to keep the building in Tennessee and use it to build more cars!
