Some mechanical menial jobs can be satisfying. At least when you can get in the zone, and see what you've accomplished at the end of the day.
I grew up on a farm. There was a lot of that. It took mental discipline, which most folks may not have an opportunity to develop in this hypercharged media world.
I didnt grow up on a farm but grew up on a good bit of land with a lot of yard work that needed to be done. I agree that some jobs like that can be satisfying but its very different from a computer based role.
At the end of the day when you have taken a large tree branch and turned it into a stacked pile of chopped wood you feel a sense of accomplishment. It doesnt feel quite the same when you've cleared 4 QA UI tickets.
