From 12.5 Hours to 93 Minutes
Before Ford’s plant introduced the moving assembly line, assembling a complete car took on average about 12.5 hours of labor; after introducing the line, each worker was fixed to one simple task and the work-in-progress moved continuously along the conveyor through the stations, compressing whole-car assembly to about 93 minutes, raising productivity more than eightfold — this leap in efficiency directly let the Model T’s price fall from an initial 850 dollars to about 260 dollars later.
The Controversial "Five Dollar Day" Decision
In 1914 Ford greatly raised workers’ daily wage to five dollars, nearly double the industry average of the time, a decision then fiercely criticized by other business owners as disrupting the whole labor market, but proven to greatly cut worker turnover and training cost and objectively to let Ford’s own workers afford the cars they built with their own hands — this logic of "high wages feeding mass consumption" was thereafter widely seen as an important early practical case of modern mass-consumer capitalism.
