You're applying nuance to a discussion which so often does not lend itself to nuance. Successive governments love to focus on the unemployment figure as though that is the mark of a healthy jobs market. As you've pointed out, it's not. It's not even close. We should be speaking about it far less, and about other, more qualitative metrics far more. We don't, though, and the cynical reason is that the unemployment metric was designed to make things appear better than they are.
