Every autumn, as families across the United States get ready to send their kids to college, the economics of higher education receive renewed attention. College is expensive and becoming more so in the U. S. The situation raises two questions: Why does it cost so much, and how can students and their families afford it?

Several studies published in the past few weeks reflect on these questions. The findings provide comfort to poor families.

First, it appears that only the minority actually pay the "high price". A study by the US Education Department's National Center for Education Statistics found that 55 percent of college students last year received some forms of help--scholarships, loans(貸款)or jobs.

Other factors are also at work. The government has increased the size of its grants (補助金)to lower-income students. Grants, unlike loans, don't have to he repaid and are awarded only to college students who have not earned a bachelor's or professional degree.

At the same time, most colleges are spending more on undergraduate education than they are collecting in tuition fees. A study, which is part of the Williams College Project on the Economics of Higher Education, reaches the conclusion that on average colleges “subsidize (贊助)” their students. The results of these studies, however, leave unanswered the questions of whether educational costs are higher than they need to be. Some experts argue that much of the college cost results from educational competition for fame, students and facilities.

This puts upward pressure on tuition, hut many colleges feel that good fame will enable them to attract students even if they charge them more.

Therefore, until something important changes in the marketplace, costs seem likely to continue rising. And American families will continue to beat down the doors of the high price "college in the end．
