A lot of blue collar people can't imagine what they'd do if they could no longer get a job in their current industry. Severance is meager, pensions are drying up, and retraining assistance (if they'd even accept it) is virtually nonexistent. When faced with "progress" making your way of life and standard of living untenable, that gets really really really scary. I'd challenge you to remain entirely rational if your job -- no, your entire industry -- went away, the bank decided to foreclose on your house (which is now worthless anyway, because there are no jobs where you live), you were unable to feed your family, and you didn't even have the money to move somewhere else where prospects were better.
On the other hand, we have a ton of tech people around here who, because of their privilege, are unable to put themselves into anyone else's shoes, even for a minute. It's basic empathy, and seems to be in short supply sometimes.
