One of the key parts of the story point out one of the realities of engineering; many engineers work in jobs that are outside of their degree field:P>
Electrical engineers have likely moved into other fields, such as software engineering, or to other engineering areas such as aerospace, or to Wall Street, among other occupations.
While it goes on to say some are no longer employed; with a 2% unemployment rate chances are if you are an EE, looking for an EE job, you have a job.
One of the challenges firms looking to hire engineers, at least a few years back, was competing with non-engineering firms for workers. I remember engineering companies complaining about Wall Street hiring engineers (and scientists) and how horrible that was; well pay salaries like on the Street and you can get all the engineers you want. Shortages of employees is usually from an unwillingness to pay what it takes to get the employees you want rather than a true shortage. That's not always the case but withe employees having had a buyer's market over the last fews years it's usually a safe bet that it is the case.
