M: (19)We all know that going to college can suck your wallet dry, leaving you thousands and thousands of dollars in debt. The question is: Is it worth it? Penelope, a senior writer for Money Magazine, has been doing the research. Thanks for joining us here.
W: Thank you.
M: The cost of going to college has increased 439% since 1982, a pretty unbelievable statistic. What is behind the surge?
W: Well, there are a number of factors, some of them pretty obvious, driving college costs. One is growing demand. There are a record number of kids graduating from high school, all wanting to go to college or at least a good portion of them. (20) And there’s less support from the government, both federal and state. But one of the most surprising factors we found was the demand from many parents to send their kids to really expensive brand-name colleges. And that creates a cycle that pushes up tuition at all colleges.
M: Is it worth it?
W: Well, in many cases, it’s probably not. People are taking out way too much debt that they don’t have realistic prospects of paying back. And going to an expensive college isn’t going to help.
M: Will the statistics keep going up?
W: We don’t think so. Actually, there’s been push by Congress to take a look at colleges that aren’t spending part of their endowments increasing financial aid or keeping tuition down. And recently, (21)some of the most expensive colleges have really boosted their financial aid so that many families from middle-class households can send their kids at much reduced costs to these schools.
