Why do people work? Of course, you may have asked yourself the same question as why you have to work. “Self-interest” in its broadest sense, including the interests of family and friends, is a basic motivation（动力）for work in all societies. But self-interest includes more than providing for living or getting wealth that people usually think. For example, a sense of duty, a feeling of competing, and a pleasure in working are other reasons for working. Studies show that most of Americans would continue to work even if they have had enough money to live comfortably.
When people work, they gain a contributing place in society. The fact that what they receive pay for their work means that what they do is needed by other people and what they are doing is necessary to society. Work can also place people in the larger class of society and provide all kinds of identities (身份) for them. In the United States, it is a cruel public fact that to do nothing is to be nothing and to do little is to be little. Work is commonly seen as the measure of an individual (个人).
Some scientists have shown some of the ways that work has effect on our lives. Generally, people who always do their favorite work are more open to new ideas and easier to get along with others, and as parents they pass these characteristics on to their children. Our work then is an important social thing that makes us know who and what we are.
