And no, not that much. Automation is of course a factor, but it came at different times for different things and don't forget that it often made things worse for workers, at least where or when they didn't have institutional support.
Having institutional support for workers (unions and a pro-labour government) is what ultimately matters. Even if some prices go up and some jobs are lost, such institutions help smooth out the transition and put pressure on businesses which would otherwise jump at the opportunity to also increase their margins.
My problem is that "it's unfair" turns it into a value judgment. Then when someone is skeptical that it can be improved without making things worse overall, or worse when someone is skeptical of a particular proposed solution, that gets turned into a moral failing.
If you perceive disagreement over the fairness of paying people badly for risky jobs, I think it's because it's so basic that people just skip over that. A small child can identify unfairness. The interesting and difficult part is what to do about it.
