Because it was outdated technology, that’s not even what you are talking about. You’re talking about a fundamental change in technology, not production methods (automation) or market/labor expansion (globalization).
Frankly, I’m not sure what point you’re even trying to make.
Fair enough, replace a disrupted technology with census tabulators who were automated. My point stands: you can't look at job losses in the affected industry to tell the whole story. You have to look at jobs in the economy at large. Automation leads to new demands elsewhere, and so does globalization.
