If you read David Clark's "The Practical Engineer" articles you will read about accidents and near misses that could have had a lot worse consequences. If they had been filming and someone got hurt you would never have seen the film. People just accepted injuries and death as part of the process. The biggest killer due to work is currently asbestosis due to people working in their own clothes with just a cloth cap to keep their hair clean. A lot of their own families have also died from the asbestos carried home. The good old days were never that good.
If anyone thinks we should go back to those days then think about having to go round to someone's house and telling them that their loved one has been killed in an industrial accident.
I work in an industrial engineering company and nowadays it's a big deal if someone cuts their finger. That is how I like it.
