The suggestion there is that people lose their jobs because they have refused to "learn or change", and that this is what unions are about.   

And in my experience, those are such gross over simplifications that they are lies. Imagine a song about a battered or deserted wife in which she says it's all her fault, because she didn't learn to pretty herself up for her hsuband and cook him different kinds of food. And she shouldn't have listened to those feminist friends of hers. That'd be the equivalent of those lines.
