I think even in single family construction, it is often the case that people specialize and the work can be quite repetitive. We had some drywall work done, notably finishing a portion of our basement. Hanging the drywall, followed by taping and mudding, followed by painting. All were done by different people,
probably with different pay scales and expectations of working conditions.
I've had people come to my house to do handyman work, and at the same age as me, they are hobbling and broken.
I suspect that one of the causes of the opioid crisis is that we had a pain crisis, caused by bad working conditions. I could imagine advising one of my kids to go into the trades, but only if they move to a country with decent labor laws, safety net, and health care. Not in the US.
