Apparently they did have some debt. Exactly how much I'm not sure.
Student loans and car loans can be quite substantial.

They had $4k in credit card debt, student loans and car payments (a Tucson and something else, but not a BMW or similar afaik). They both worked and he made ~$61k iirc. Assuming she made only $40K (considering that she is in the specific field she's degreed in and graduated a few years before he did, I think that's a HUGELY safe number). So, they'd be making at least $100k. His benefits would be stellar with HD and would cover both LH and Cooper. They had a nice condo in Marietta and at least one newer car, but nothing fancy at all. I think they were, as LH said, having no more trouble than others in this economy. Actually, it seems like with both employed, her p/t only, etc., etc. they were doing a whole heck of a lot better than many people who've really suffered economically over the past few years. Idk, maybe he gambles.
