I think it is a different economy. I also question where the money to buy cars, take vacations, buy TV's etc., is coming from.
College graduates are getting around 36k - 40k to start. That is hardly enough to pay rent, utilities, buy gas and shop at Food Lion (if you can find one) in No. VA.
It also seems to me that people are getting rehired after having been layed off for a while, but at a discount of maybe 15% from what they were making previously for the same job, while prices at the grocery store and the mall and the gas station have been going up.
So, are they draining their 401(k)'s or whatever equity they have in their homes? Credit cards? I have no idea. The cheap money helps (everyone that can has refinanced twice), but it's got to be more than that.
