The way economic news is presented has been annoying me lately, too. It's called the wealth effect, that people feel wealthier due to their house being worth more, so they spend more.
I just can't wrap my head around what all those people are thinking out there... a number on a piece of paper says that an asset you own, that you probably aren't planning to sell anyway, and if you did you'd pay a correlated price for a replacement, is worth X% more than last year, and this is supposed to make you waste more money???
When my investments appreciate I know I'm worth more, but rationally if I were to spend it I wouldn't be worth as much anymore! It's like these people don't understand what it means to get ahead.
