Thats gloomy.
You miss 1 major thing though. What is the reason that China can produce a blender for $10?
Once you get wealth pumped into China, you get people wanting more things, just like you see in every other developed country. That grows Ag demand, and you then see the US fill the demand. There are no profits in the long run right, so this is simply an adjustment in the global economy. China is consuming massive amounts of stuff right now, and its growing. Its middle class is also growing, and they will want people to produce things.
In capitalism there are winners and losers. The losers lost because they could not compete, and the winners won because they did it better. You can have illegal activity, and government regulation can be inserted there, but on the whole, we want global competition.
