It's tempting to use macro trends, like the advent of workplace safety, to confirm one's existing beliefs. Economy-wide changes like this are pretty much without exception driven by a bunch of different factors working together and you can pretty much always find some to cherry pick to back whatever your opinion is that minute.

Pretty much all the current literature about workplace safety seems to follow one ideological bent. I commend the author for at least hitting the topic from a wide array of angles even if he missed a couple.
