Well, my point wasn't really that the job has gotten easier, it's that some people simply prefer doing that kind of work.
I remember being in a meeting once when a manager looked out at the guys on a scaffold cleaning the windows and remarked "at least we don't have to be out there like them." My first thought was that they were probably thinking "at least we don't have to be inside like them."
While I can understand the sentiment, I think most of this is fantasy. A lot of people vastly underestimate the toll manual labor takes on one's body. It may be nice to ponder "Wow, it must be so great to work out in the sunshine all day!", compare anyone doing physical labor (and I count extended driving in that) age 50+ with any office worker 50+. Sure, anyone 50+ has standard aches and pains, but I've seen many physical laborers dealing with constant pain and a lot of degenerative diseases at that age.
