Unless I misread the article, it's about blue-collar workers losing their manufacturing jobs due to globalization. I don't know what the typical career progression in manufacturing looks like, but if you can be replaced by some freshly hired 22 year old in China, you're probably in the bottom rung. So it's not like that hypothetical 40 year old was suddenly thrown back into the bottom rung after a successful career where their superior experience protected them from competing with 22 year olds. Their well-paying job at the bottom rung disappeared, with the only alternatives being retraining for less well-paying jobs in the bottom rung of other industries or staying unemployed. It appears many stayed unemployed.

I think they should be given sufficient support to bridge the gap while they retrain; potentially even before their jobs disappear. That seems strictly preferable to unemployment.
