        businesses produce only certain kinds of goods or services, such as cars,
        tacos, or gardening services. This feature of production is known
        as specialization. A high degree of specialization is a key part of the
        economic system in the United States and all other industrialized
        economies. When businesses specialize, they focus on providing a
        particular product or type of product. For instance, some large
        companies produce only automobiles and trucks, or even special parts of
        cars and trucks, such as tires. At almost all businesses, when
        goods and services are produced, labor is divided among workers, with
        different employees responsible for completing different tasks. This is
        known as division of labor. For example, the individual parts of cars
        and televisions are made by many different workers and then put together
        in an assembly line. Other well-known examples of this specialization
        and division of labor are seen in the production of computers and
        electrical appliances. But even kitchens in large restaurants have
        different chefs for different items, and professional workers such as
        doctors and dentists have also become more specialized during the past
        century.
