Extremely well written and documented history of Black Lung Disease and the toll it has taken on miners. Definitely a “we can show you better than we can tell you” accounting of the bleak reality imposed on miners by politicians, medical professionals, and most of all, the capitalist mine operators who profit enough to pay off of the first two while using jobs that can literally kill people to get miners to betray their own best interests. Very academic by nature, so sometimes pacing was an issue, but highly recommended and likely to be a frequent reference point for me for a long time.
