Have you ever worked in a factory? I find the people most enthusiastic about manufacturing are the ones least likely to have stood at a station in a factory performing manufacturing "work" - the vast majority of which is mind-numbingly boring and repetitive yet with minimal opportunities for passing the time with idle social interaction or chit-chat. Of all the non-professional work I've done, it was easily the least enjoyable. Even if it paid a bit less and demanded more physically, unskilled construction work was enjoyable in comparison. Even kitchen portering provided more stimulation - at least there was plenty of social interaction. This romanticization of factory work is weird.
