I think Bike Rider’s point is the people they interviewed were generally clueless about the facts of the housing bubble. Now, I’m sure if they had focused on people who were likely home buyers in the next year or two they would have gotten more educated answers. But with a “man on the street” interview you’re not looking for rigorous analysis, just to get an impression of what the “everyman” thinks.
(But yeah, watching FOX news for anything other than the entertainment of laughing at it isn’t a good idea)
