The weather in the South is very suitable for profitable economic growth. The South should concentrate in manufacturing/heavy industrial. making products that is where the most money. Don't let the North control anything. they will bust like a balloon.
There are all kind of products waiting to be made. The South need to take control. If you don't know it learn quick like the Japanese. They respect people so they can learn from them and make things better then them. That is the Japanese way.
