Harlan County USA might surprise viewers that even in the 1970s, large communities existed without indoor plumbing. This documentary is disturbing in that even during the late 20th century, conditions like the one in the movie still existed. Viewers experience many different things as the documentary unfolds; the dangers and pains of working in a coal mine, the corruption of unions and their non-union opposition, and the mind set of American laborers. Harlan County USA is a great documentary and not to be missed by those interested in American labor and the coal mining industry.
