Yes, leaving out the consumption of materials in the form of goods manufactured elsewhere is such a giant, glaring hole in the logic that it strains credibility to believe it's mere oversight. It looks like deliberate misinformation.
No, I read the whole thing. It talks about imports and exports of raw material, but excludes the import of those same materials in the form of goods manufactured elsewhere. For example, raw copper would be included, but copper coils in a refrigerator manufactured in Korea would not. That seems like an extremely arbitrary distinction, and one which would likely change the graphs presented significantly.
I was also thinking about this. We manufacture more in dollar amounts but I'm curious if that translates into quantity amounts. Higher tech manufacturing like chips instead of nuts and bolts, beams, industrial equipment, etc.
I have to agree with you. The article is fatally flawed unless it can address these issues you mention. I'm surprised the readers here didn't catch it but I suppose they were busy discussing how quantities are priced at the supermarket.
