Content: Once that happened, people faced a choice they still
        face today: In terms of time, money, and other things that they could
        do, is it less expensive to make something themselves or to let someone
        else produce it and buy it from them? Over the years, most people and
        businesses realized that they could make better use of their time and
        resources by concentrating on one particular kind of work, rather than
        trying to produce for themselves all the items they want to consume. Most people now work in jobs where they do one kind of work; they are
        carpenters, bankers, cooks, mechanics, and so forth. Likewise, most
        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.
