Digging deeper, something is amiss with the reference the article sites.

According to this cited article, Item 4 there are 13 million American manufacturing jobs.
Buried well down, item 15, foreign-owned firms employed 5.3 million workers in America in the manufacturing sector.
The way I was taught math, that represents around 40% of the American manufacturing jobs are in non-American-owned companies. Yet the article identifies this (minimizing the impact) as only 16.4%. Are Americans really this bad at math? Or this good at obfuscation? But 40% is really signifying 'branch plant economy', similar to Canada..
Agriculture is relevant only as far as you proclaim to to be. The discussion is neither about agriculture nor agricultural productivity. Yield per acre is now a much better indicator of agricultural success than farm labor productivity.
I have absolutely no idea where you got the notion that I thought Canada's educational system is inferior to that of America. That notion is just silly. What I am saying is that the government is not putting enough public money into our highly successful and highly effective apprenticeship programs. A program is only as influential to our economy as the number of students who can get into it.
