You kind of made my point. Not as many people are "locked in a factory 80 hours a week" that is driven by technology (which includes hardware tech).
When a new car manufacturing plant opens and says they will create 250 jobs that is far less than it was 20-30 years ago when a new plant opened. Robotic manufacturing, software, etc. have driven that. Pick any industry and technology will have driven some jobs out of it.
