Yes, I think that has a lot to do with it.
A lot of couples I know of relied on bringing in two incomes to maintain their lifestyles and some were so seriously overextended in debt to maintain this lifestyle that they couldn't afford to service the debt any longer when one of them lost their job, so they wound up losing their homes or bankrupting.
Perhaps extending credit to people who could barely afford to pay for it was a good short term strategy to appear to stimulate the economy, but it has proven to be a bad longer term solution, IMO.
