For example, if music schools were to educate many more oboe players than could get positions playing the oboe, we might find that many of them would have to get jobs in other fields. Lacking training for other skilled fields, some oboe players might be unable to get any jobs at all. This would be an instance of structural unemployment.
Structural unemployment raises some questions.
On the other hand, people with little in the way of training suffer more than average unemployment in most of the industrialized countries. This suggests that structural unemployment is really quite an important problem in the industrialized countries at the end of the twentieth century.
