Of course it's anecdotal evidence, but I listened to a podcast a while ago (don't remember which one) that invited a government clerk that helped people find retraining programs. According to her, her department has so few people applying that they would accept literally any request for training - even if it had nothing to do with what the funds were allocated for (in this case retraining from coal to solar). According to her, a big part of the problem is you have people in (usually small) towns whose parents lived their entire lives working coal, and think that the only way to be a man is to work it too.
