The Friday afternoon computer science class at Berea College looks much like similar classes on campuses all over America. But there’s one big difference. While a four-year undergraduate degree at Berea costs nearly $100,000, these students will never see a bill for tuition. The average American takes out $24,000 in student loans to pay for their university education. Of those loans, about 14 percent slide into default. However, at this college in the small town of Berea, Kentucky, graduates rarely have to cope with that kind of crushing student debt. Berea students pay for their education - as they study - by working at jobs provided by the college.
