1. 5 million unemployed people 2. very highly sought after workers
The employers complaining about people in group 2 being scarce are merely not paying enough. The workers complaining in group 1 need more skills that the market wants. They're at different ends of the spectrum.
Other than that they live in the same country, they really don't have much to do with each other. Whether you can convert people from group 1 to group 2 is an interesting question, but generally if it were easy to be in group 2, a lot more people would be in it.
