An answer to the Easterlin paradox

In Stumbling on Happiness, Daniel Gilbert writes about a study where:

[R]esearchers telephoned people in different parts of the country and asked them how satisfied they were with their lives. When people who lived in cities that happened to be having nice weather that day imagined their lives, they reported that their lives were relatively happy; but when people who lived in cities that happened to be having bad weather that day imagined their lives, they reported that their lives were relatively unhappy.

This seems like a good answer to the Easterlin paradox. If today's weather has a big influence on my assessment of how satisfied I am with my life overall, then obviously asking people how satisfied they are with their lives is not, in fact, a good measure of how good their lives actually are. So a failure to find a correlation between people's self-reports of their overall life satisfaction with their level of wealth proves nothing. Maybe driving an Audi R8 does make your life happier, you're just not always cognizant of it. Like, for example, when it's raining, and you just got back from walking your daughter-in-law's dog who you're dog-sitting for the weekend, and you get a call from a telephone research person asking how happy you are about your life as a whole, and your hair is still wet and it's dripping on the floor, and you're cold.
