Zillow.com is out with a survey finding that:

62% of U.S. Homeowners believe their home’s value has increased or stayed the same in the past year. In reality, 77% of U.S. homes have declined in value over the past 12 months.

To a large extent, this simply confirms that humans will be humans, as when most people say they're above-average (then who is average?). But it's also a statement about the times we're in and just how much people have come to expect homes to never depreciate. Time to wake up folks, the game has changed.
