White-collar

The earliest known use of white collar in print to distinguish types of workers dates to 1914, when a writer in Chicago Commerce described white-collar men as clerks, bookkeepers, cashiers, and office workers, separating them from men who work with uniforms and overalls and carry the dinner pails. The social distinction was already embedded in American culture. A white shirt that stayed clean through the workday was a signal that the wearer's labor was mental, not physical.

Upton Sinclair gave the term its political edge. In The Brass Check, published in 1919, he described how petty office workers, because they were allowed to wear a white collar, regarded themselves as members of the capitalist class and became the most bitter despisers of union workingmen. By the 1930s, white-collar was standard vocabulary in both journalism and sociology. The companion term blue-collar, referring to the durable blue work shirts that hid factory grime, was in use by 1924.

Sociologist C. Wright Mills extended the analysis in White Collar: The American Middle Classes, published in 1951. Mills argued that white-collar workers had become a new class, neither owners of capital nor traditional laborers, defined by their proximity to information rather than to material production. The book documented how the number of white-collar positions in the United States had surpassed blue-collar jobs for the first time in the late 1940s.

The clothing distinction that created the term has largely vanished. Silicon Valley executives wear hoodies. Factory floors are increasingly automated and climate-controlled. The vocabulary persists because it was never really about shirts. It was about a hierarchy in which thinking was ranked above making, and clean hands signaled higher status than calloused ones.
