The market meltdown is not just a pocketbook issue — it’s become a psychological one. The economy’s downward spiral is taking our sense of well being with it. And as our anxiety and panic levels rise, we are creating a kind of feedback loop: The less confidence we have in our future, the less likely we are to go out and spend. That behavior, of course, only diminishes our chances of economic recovery.
