I first saw this notion at: Wallet Pop and followed the link to Fox Business .
I wasn't sure about the idea because personally I tend to not shop when I'm feeling down but when I have to, I get what I need and get out of there.
Maybe it has to do with some basic feelings toward shopping and "things" in general?
This also brings up another question. Are Americans that unhappy?? Because it seems like there's always a whole lotta shopping going on!
