By Upton Sinclair, who always takes the side of the underdog and shows people how hard and unfair life was for the lower classes in his time (i.e. early 20th century), King Coal is about a well-to-do college student, who leans to the left politically. His older brother and friends tell him that all the news and complaints of poor treatment of coal minors is hog wash. He decides to spend his summer as a miner.
He takes on the clothing of a working man and goes to North Valley where he gets work in a mine. He has no idea how much worse things were than he imagined. He makes friends with the workers, lives amongst them and sympathizes with them. He gets the same bad treatment. He faces the same problems – high rents in the mining housing, bad food at the canteen, exorbitant prices at the general store. When he helps the men organize and request, not a union, but someone to check that the coal loads are weighed right, he lands in jail. The judge is in bed with the mine owners. Upon release he’s followed and when a reporter prints his story . . . well, on and on it goes, injustice upon injustice.
The story is compelling and Sinclair creates likable characters a few that middle class and progressive wealthy folk would take to. It’s still a relevant story and should be read in history classes. If I taught history, I’d have some students read this, others read The Jungle and others read Oil! and then compare notes.
