As the article did point out certain industries - I got the gist of the article as the sheer number of jobs being lost and not replaced. Now once again, not all jobs that go overseas is unionized - not by a long shot. Therefore, you cannot lay this at the feet of the evil unions. AS popular as it was a few years ago, it is just outdated.
How do you explain the loss of non-union jobs - what did they do wrong that they deserved to loose their jobs?
