My construction experience was mostly moving heavy crap from one pile to another pile, so I can't really judge the relative skill of individual electricians or plumbers. However, an unskilled or sloppy electrician will have a pretty low life expectancy. Edit: Sorry. That might have seemed snarky. Most of these jobs have pretty strict licensing and certification requirements. An improperly wired or plumbed house is pretty dangerous, so a lot of effort is put into making sure that does not happen. I think the unskilled electricians would be filtered out earlier in their training.
