Let me clarify my position by going back to simple basics.
In a country there are a lot of people. These people need to have certain things to live in some quality of life: clothing, footwear, transportation, food, shelter. They also want certain things to improve their quality of life: entertainment, creative outlets like hobbies, specific forms of the above 5 that are slicker and nicer than the dirt basic forms of those things.
In order to get these things, the people have to produce them, either make them themselves for their own use (spin flax and weave it into cloth, make foot wrappings out of a tough material like leather, build a wagon and train a draft animal to pull it or engineer an alternative vehicle, grow gardens and hunt, build a house or log cabin), or dedicate their time to making lots of one thing and trade to others for something the other devote their time to making.
In that process, everybody has what they need to live pleasantly because they can trade what they make with others who make something they need. All of this can occur within the confines of one country, and only some raw materials not in that country need be imported from other places.
In America, we can make anything our people need to live comfortably and entertain themselves. We have done it, with some minor exceptions like fruits and cute design of other things we may like to have that is not necessary to life here. We trade these things back and forth and have a high quality of life.
The whole point of trade is to get these things for ourselves, the people of the country. To make the process more efficient we use a medium of exchange that is easy to carry around and give to one another. So, instead of trading 20 chickens for a cow, we can sell the twenty chickens and buy a cow.
Prices don't matter because if you make plenty of compensation for making a thing that others need, you have no problem paying the price that others charge for the things they make that you need. Market forces stabilize that process.
So, give me some reason why we have to mix saliva with Japan, China and Korea? It obviously is not to our advantage because it is currently being proved by simple observation that it is not to our advantage.
