There are a few major questions that need to be answered in all of this...
1. Are college students getting a better education to coincide with all of the tuition hikes they face during their time in college?
2. How many students with good enough academics to get into college are not going because they can't afford the tuition?
3. As the tuition continues to grow higher and higher what plans are being made now to account for a significant drop in enrollment in the future when the cost becomes so great that a larger percentage of high school students can't afford to pay for college?
Currently the answers are...
1. The average amount of money spent per student currently is at the same level it was at in 2002. So to answer the question... students are currently spending more and getting less for their money. That is a problem.
2. I couldn't find specific numbers for this question but based on record enrollments it hasn't become a big issue yet. It isn't far off though as current grads are finishing school with a ton of debt and entering a job market that isn't exactly ripe with jobs for all of them. Who wants to go rack up a huge chunk of debt and then face the prospect of not being able to find a job?
3. At some point enrollment is going to face a sharp decline if the current price of tuition keeps rising. What will happen to these universities when that happens? State funding continues to decline and the only people who can pick up the tab are the students. A sharp decline in enrollment will be devestating. How many kids will want to attend ISU, UNI, or Iowa when it costs as much as Duke ($51,000) per year? They won't be getting a "Duke" education that is for sure but the BOR will have no choice but to either drastically cut programs offered or hike tuition to levels unheard of for public universities.
In my opinion, this is as big of an issue as the current state of the economy, gas prices, or universal health care, if not greater. Sad that it gets almost no attention besides from those who are directly affected.
Although, to to be honest, that is why those other issues mentioned above are so big. Because they affect everyone now instead of later.
