Fair enough. GM is near bankruptcy these days because of its massive employee pension and health costs.
Robots and computers don't get sick and they don't retire. It is not surprising that employers would rather automate than hire more employees.
I don't really see a solution to this. A few generations back, mechanization wiped out millions of agricultural jobs in this country, but the long-term effects for the workers that were displaced were positive.
Good post and some (most of) thoughtfull comments.
