A college freshman squirms anxiously on a chair in my office, his eyes avoiding mine, those of his English professor, as he explains that he hasn't finished his paper, which was due two days ago. 'I just haven' t had the time,' he says. 'Are you carrying a heavy course load?' 'Fifteen hours,' he says—a normal load. 'Are you working a lot?' 'No, sir, not much. About 30 hours a week.' 'That's a lot. Do you have to work that much?' 'Yeah, I have to pay for my car.' 'Do you really need a car?' 'Yeah, I need it to get to work.' This student isn't unusual, indeed, he probably typifies today's college and high school students. Yet in all the lengthy analyses of what's wrong with American education, I have not heard employment by students being blamed. I have beard drugs blamed and television that universal scapegoat. I have heard elaborate theories about the decline of the family, of religion, and of authority, as well as other sociological theories. But nobody blames student employment. The world seems to have accepted the part-time job as a normal feature of adolescence. Parents often endorse this employment by claiming that it teaches the value of the dollar. Students worked so that they could spend $ 60 to $100 a week on designer jeans, rock concerts, stereo and video systems, and, of course, cars. They were living lives of luxury, buying items on which their parents refused to throw hard-earned money away. How students spend their money is their business, not mine. But as a teacher, I have witnessed the effects of their employment. I know that students who work all evening aren't ready for studying when they get home from work. Moreover, because they work so hard and have ready cash, they feel that they deserve to have fun instead of spending all their free time studying. Clearly individual students will pay the price for lack of adequate time studying, but the problem goes be- yond individual. It extends to schools and colleges that are finding it difficult to demand quantity or quality of work from students. Perhaps the reason American education has declined so markedly is because America has raised a generation of part-time students. And perhaps our economy will continue to decline as full-time students from Japan and Europe continue to outperform. our part-time students.What attitude do parents often hold toward student employment?A．They think going to school is enough.B．They don' t want their children to hold regular jobs.C．They often think employment can teach their children the value of money.D．They think helping around the house is even more important than holding regular jobs.
