I'm not talking about this specific case right now. The problem of lack of jobs is systemic, and applies to all professions, with a strong tendency to be even more pressing. Due to automation, software and other things the number of jobs, especially low skilled ones is shrinking. Yes, you can educate yourself, and anyone can/should, but in the end, one quarter of the people will be undereducated just because the bar is higher, and will still not be able to find a better job. We, as a mankind, have to seriously consider radical solutions to this problem, and not focus short term on any specific industry.
Should be start decreasing working hours due to productivity increase, or just invent bullshit jobs just to keep people employed? Or to progress to Star Trek economy where people will be provided with all basic needs and work only on what they would like to? I know what I would like to happen, but I also fear what would happen. Talking only about unions, Detroit or any specific industry or place is not going to "fix" the global problem, and that is that the need for jobs is decreasing, and number of people is rising. We should tackle that problem instead.
Sorry for rambling, it might only be tangentially relevant to the article and discussion, but what I see in all this cases is just this problem. Ok, I might be overgeneralizing, since I'm software engineer, but not to much.
