Yes and no. It can speak to structural inefficiencies in the economy. For instance, I am a Computational Scientist with a decade of experience in scientific research, publications, etc. It would be a massive waste of my training to be working in an unrelated field, for instance.
Underemployment is a very real thing, and it hurts the entire economy. We as a society have a vested interest in ensuring that highly productive roles (data science, medicine, etc.) are filled, because thelse positions are more productive and boost the aggregate economy. To say nothing of the likely higher salary and job satisfaction that comes with a 'good fit'.
