The concept of value added is when you take a resource, say a tree, and you process it, into 2 by 4s for construction, furniture, etc.
It seems to me the US is masterful at creating "value added" work. In econbrowser take a look at the graphic model for the banking industry say when I worked in banks in the 80s. Then scroll down and look at today's model.
Something I have to ask myself, how much is the so call economic growth from real growth or from make work, add costs, be highly inefficient, do nothing for the economy, type of work in the model?
