The author talks about the philosophy of work. He successfully explains the differences between what or who is benefiting from ergonomics or from the ergonomist. Employer or employee? Does the state have the right to come forth & make guidelines on ergonomics,ethics, or how they're applied? Karl Marx or Frierdrich Engels knew nothing of ergonomics when they wrote the "Communist Manifesto" 1848. Is ergonomics for a Capitalist society or communist society. W.T.Singleton answered the question in true non-bias form so the reader can form their own opinion on the topics. Most authors claim to be bias on issues but make their views look politically correct. This book allows the reader to form their own opinion. Knowledge is what you believe to be true. If you don't believe something to be true you have no knowledge of it. Allowing the reader or people to form their own opinion is truly the way to educate the society. Well done "Singleton"
