I don't feel shame for shaming unjust downvoters (that said, I've upvoted your comment, too). A short googling for for "history of workplace safety in the us" reveals that unions had a hand in at least that. Probably in several other things you take for granted. In my opinion it's a mistake to think that things like that cannot deteriorate away after they've been achieved once.
