You also have to take into account that kids these days do not want to get into a skilled trade. And even then the companies within these industries are doing everything they can to get rid of that skill.
I work in the power industry. Part of my job is to splice lead covered cable(PILC). The majority of companies are starting to use cold shrink splicing kits(preassembled) as well as heat shrinks(made in belgium). Yes it's ten times easier, however you take the skill away from the posistion and you have more leverage to not make a decent contract offer based upon the amount of skill it takes to perform such a job.
Union jobs and wages are deteriorating all across the nation. Why because with the jobs getting easier you can higher people willing to accept a job at the fraction of the cost we get paid to do it now. It's no wonder that union companies shut their doors and reopen 3 months later under a new name(non union) and pay the employees crap.
As someone else said the same piece of metal could be drastically different in it's molecular makeup depending where it comes from. Same as oil, the US extracts a lot of oil from this part of the world, but being that it is rich in Sulfer and other non useful contaminents it's sold to Japan where they can eat up the more expensive cost of refining it.
It's not gonna change until the next big war. You can count on there being another(ever heard of the Franco-German empire). Well they are pretty much partners now in trying to control the economic policy within the EU. Why do you think they want this? Everyone knows that you cannot beat America on your own, but if we team up it could happen. Be nice to Canada they may be the only ones willing to help us when the chips are down.
