Can't speak to that specifically, but one thing I have heard in other similar cases is that the people who try the retraining programs, find that they don't work. Some people can sit in a classroom and listen to a lecture and learn something, other people learn by doing something on the job.

If we still had widespread apprenticeship as a way to learn, this would be fine. Classroom training isn't really the greatest way to learn something. But it's the way our society has doubled down on in the last generation or so, to the point that high schools shut down shop class programs and expanded AP, regarding anyone who didn't go to college as a failure.

Again, I don't know if it applies to the case you're discussing, just raising it as a possible explanation.
