Here's an interesting New York Times article that says the idea that American workers have a skills gap is nonsense:
This is interesting because it calls the concern about a skills gap a 'zombie idea', one that isn't true but that nonetheless refuses to die. I'm interested in that sort of thing, that "how we know what isn't so" thing. Also, it mentions how the idea benefits corporations and their executives.
In fact, this is a good time to mention the book How We Know What Isn't So by Thomas Gilovich, which I very much enjoyed. It explains misinformation and wrong beliefs by examining biases and heuristics in our psychology. I read it in 2009, and I recommend it.
