Henry Ford, the famous US inventor and car manufacturer, once said, “The business of America is business.” By this he meant that the US way of life is based on the values of the business world. Few would argue with Ford’s statement. A brief glimpse at a daily newspaper vividly shows how much people in the United States think about business. For example, nearly every newspaper has a business section, in which the deals and projects, finances and management, stock prices and labor problems of corporations are reported daily. In addition, business news can appear in every other section. Most national news has an important financial aspect to it. Welfare, foreign aid, the federal budget, and the policies of the Federal Reserve Bank are all heavily affected by business. Moreover, business news appears in some of the unlikeliest places. The world of arts and entertainment is often referred to as “the entertainment industry” or “show business”. The positive side of Henry Ford’s statement can be seen in the prosperity that business has brought to US life. One of the most important reasons so many people from all over the world come to live in the United States is the dream of a better job. Jobs are produced in abundance (大量地) because the US economic system is driven by competition. People believe that this system creates more wealth, more jobs, and a materially better way of life. The negative side of Henry Ford’s statement, however, can be seen when the word business is taken to mean big business. And the term big business -- referring to the biggest companies, is seen in opposition to labor. Throughout US history working people have had to fight hard for higher wages, better working conditions, and the right to form unions. Today, many of the old labor disputes are over, but there is still some employee anxiety. Downsizing -- the laying off of thousands of workers to keep expenses low and profits high -- creates feelings of insecurity for many.11. The United States is a typical country _____.
