If this were a widespread attitude surely the office workers would be paid less than physical laborers (and, frankly, they probably should be). I do a lot of physical work (that's my two primary jobs) and people don't spend their time fuming over people with soft hands—that's kind of a "loser" thing.
At the same time, that office worker has to take time out of their free time to get exercise while the Amazon driver gets paid to exercise on the job. There's a lot of health risk with not getting daily exercise.
I'm guessing the most spoiled people in the world wouldn't be working at all. This sort of contempt is a very specific and odd attitude to have.
