The student loan market has a lot of factors that seem to say "Stay the heck away!": they're relatively easy to qualify for, college costs have increased far more rapidly than general consumer prices, we now seem to feel that EVERYONE SHOULD HAVE A COLLEGE EDUCATION. ELEVENTY!!!, and most importantly, the job outlook for many (most?) college grads is to put it mildly, pathetic.
This graph from the Washington Post piece points out some evidence that we might be seeing the beginning of the next "bubble pop". Although they're a fairly small part of the overall consumer loan market, student loans are more likely to be 90+ days past due than any other loan class. And the percentage is growing pretty rapidly.
Luckily, the Unknown Daughter gets free tuition at Unknown University. We still have a half-dozen years until we have to shell out for college, but it'll take a lot to justify her going somewhere other than to my (fairly low-cost) school.
