Query: Labor Can Do No Wrong

This old book (written in the 1950s) is published by a labor union because mainstream publishers would not touch it. Union people love this book because it makes union leaders out to be martyrs and saviors of the world, standing up to those mean, greedy old corporate capitalists. For these authors, the story of labor is black and white, no shades of gray. Labor can do no wrong and never has done any wrong. The Molly Maguires were not draft dodgers and murderers, but innocent martyrs who got framed. The Homestead rioters were poor oppressed immigrants asserting their right to take control of steel mills, and are not not to be blamed for beating and shooting the police or trying to assassinate the company president. The western miners headed by Communist Big Bill Haywood didn't really blow up mines with dynamite, the mine owners did it just so they could blame the union. This book isn't history, it's a cartoon of history. Don't look for any balance, objectivity or nuance here.
