It isn't surprising to me. Most of the people that post and reply on this board are well educated, established professionals. They aren't the ones that have been hurt, and have probably done pretty well as the stock market has more than doubled since early 2009, and many have been able to refinance their homes. It really isn't a random sample of Americans.
The ones that have been hurt are the under educated, less employable workers like union members, truck drivers and box carriers.
Also, how many people would still say they are "better off" when you add their portion of the extra debt we've accumulated over the last 4 years? What about when the bond market bubble and stock market bubble collapses and their 401ks take a big hit? I think there are a lot of people that think they are "better off" because they don't even realize how this economy is artificially propped up with duct tape and chewing gum.
