The 8% interest on the loans seems high to me. Around here (Poland), a standard credit card is at 10% interest, and student loans should be much safer for the bank.
10% interest on a credit card would be pretty low for the US, AFAICT. Most first-time cards come with 23-24% interest, at least when I started searching for one.

I lean fairly liberal, but I think we can make significant strides with this issue in the US by simply changing what max interest rates are and how this interest compounds. The way things work right now truly feels like robbery when you're in the thick of it.
So an equivalent U.S. interest rate (using the fed rate and the same spread) would be around 3%.
