In the last century, the nature of work, along with Americans' attitudes toward work, has changed significantly. For one thing, work is now more mental, less physical, and a lot less dangerous than it used to be. According to economic historian Stuart Bruchey, from 1880 to 1900, about 35,000 workers a year were killed on the job, and 500,000 were injured in work-related accidents. Today, there are fewer dangerous jobs; even factories now use automated machines that have greatly reduced the risk of injury. In 1998, for example, only 5,100 workers were killed on the job. A second change has occurred in the number of hours worked. In the late nineteenth century, low-wage factory workers averaged about sixty hours a week on the job and worked six days a week, resting only on Sundays. At the same time, according to economist Dora Costa of MIT, the highest-paid 10 percent of workers worked about two hours less per day. Now, those numbers are almost reversed. Today's highest-paid 10 percent of employees work about 8.5 hours per day, and the lowest-paid work about 7.5 hours per day. One final change concerns workers' expectations about their jobs. In the late 1800s, most people
