That seems like a gross oversimplification. Retraining could fit as a component of a much larger plan to tackle the issues facing the job market and employability of people in these fields. Or maybe it can't. Either way, oversimplifying doesn't further the discussion.

It doesn't have to be from coal miner to software engineer, or some kind of massive transformation. Skills training and education for adults is more than that, IMO.
