I grew up in pretty severe poverty, the adults around me didn’t work glamorous jobs but they all took pride in doing a good job. Even sanitation jobs, which were pretty common in the family. They would actually say something pretty similar to what the guy wrote - that if you’re going to spend so many hours of your life doing it, it’s taking pride in a job well done, the relationships you have with your colleagues and customers you get to know, and things like that that you connect with emotionally. Spending 50 years doing a job where you try to dissociate emotionally as best you can sounds something like a nightmare, and what would a person who behaves like that be like to work with?
