Factories in the Mechanical Age
This is how so many in the Saginaw Valley made a living in the mid twentyth century. This video is from 1936 but the core of the method was the same when I entered an assembly plant in 1973. With each year, there was fewer people working and more automation. By the end of my time (2001) at least half of these people would be gone from their stations and the work done by machinery.
