Mass Production and the Ford Model-TThe production of large amounts of products on an assembly line is called mass production. Theadventof the production line changed the way people worked and lived in the 20th century. This method did not become popular until Henry Ford's Ford Motor Company began manufacturing the Model-T car in 1908.Henry Ford was the inventor of the car and president of the company. He was always searching for a more efficient method of production. In 1913 he introduced moving assembly lines to his production plants. By 1914, the Ford assembly line was so efficient that it took 93 minutes to produce one Model-T. They came off the assembly line every 3 minutes. Ford produced more cars than all of its competitors combined.In addition, Ford's assembly line introduced a new level of worker safety. This method of having workers stay in an assigned position led to fewer accidents. Ford also shocked the nation with an unprecedented $5 per day pay scale. This effort on the part of Ford to attract talented workers more than doubled the worker's minimum wage. In 1908, the price for a Model-T was $825, and it fell every year after. By 1916, the price of the Model-T had dropped to $360. There were more Model-Ts than any other car on the road. The only colour available in this model was black. This was because black paint was cheaper and dried faster, keeping production costs down. Henry Ford was heard to have joked, "Any customer can have a car painted any colour he wants, so long asitis black."By the 1920s, 15 million Model-Ts had been produced. This record held for 30 years. Many people learned to drive in a Model.-T. They had very fond memories of the car.The Model-T revolution changed the way people around the world work and travel. Now, assembly lines employ people in every industrial nation. Also, people use cars in their everyday lives.What is the author’s purpose in writing this passage...
