Actually, the national average for a RN with about 5 years experience is about $25/hour. The average for an auto worker on the line is about $26/hour. Benefits for RNs vary by where they work, but on average, RNs receive pretty good benefits as part of their compensation. Maybe UAW workers may make more, but not much more.
However, I guess your point is a UAW worker’s job is not as valuable as a RN’s job. That might be true, but you could make the same case that a pro athlete, movie star, banking executive, and a bunch of other professions aren’t as valuable as a RN’s job. Should we start adjusting all salaries based on who we think is the most valuable?
However, you can’t really blame the average worker on the line for poor quality. They didn’t engineer the vehicles. They just put them together. The manufacturer dictated what was built and how it was built.
