A recent article in Slate online magazine presents the current state of household debt in the US. This graph appears there:

What’s interesting is that while someone with a mortgage probably has an offsetting asset of approximately equal value, there’s no asset of value to offset the credit card debt, the car is probably not worth as much as the loan balance, and the prospects of paying off those student loans are getting grimmer by the day (although a college degree is still a good investment compared to the alternatives!)

So I’d be worried about those credit card balances, and that auto loan, first.
