Reminder of why these people should not ever be in charge again.
A pair of Nike Air Jordan's has an energy signature - a gold pair of earrings, a trip to Paris... because a person can't see fossil being burned doesn't mean it's not happening. Running a factory, transporting merchandise, or paying employees who will then buy things manufactured and transported by fossil fuels is just as real 'a use' as a car driving down a street.
This newest 'cash for clunkers' plan is based on people being stupid - your energy 'signature' is closely correlated with how much money you spend every year. Period. Which puts the worst abusers on record living in and around Washington DC.
