Have you ever worked in a manufacturing job? Surveys have shown that people are much happier, on average, with their service jobs than they were in the past when manufacturing was more prevalent. That's because factory work involves doing dangerous, repetitive, mind numbing work in a loud, often overcrowded, odorous, and hot space. It's a meme that everyone wants to bring back manufacturing jobs, but no one actually wants to work in manufacturing. People want cozy office jobs.
