Why do you say that people don't want to work on Industrial jobs and they are the "worst"? I see this point of view regularly regurgitated on HN and I am genuinely puzzled.

That might be true for HN (folks who prefer working at a desk) but that is NOT true for a vast majority of people.

I have both friends and family who love to work on the factory floor/shop - it is more varied and interesting for them. More interaction, more visible output of labour and they don't need to join a Gym as they get enough physical movement in their daily job. They despise the idea of sitting at a desk the whole day.
