Pigou club slogan

Al Gore comes up with the perfect rhyming slogan for Greg Mankiw's Pigou Club:

"The answer is to end our reliance on carbon-based fuels," he said in a speech in Washington.

"When you connect the dots, it turns out that the real solutions to the climate crisis are the very same measures needed to renew our economy and escape the trap of ever-rising energy prices."

To secure this green revolution, Mr Gore said the single most important policy change would be to "tax what we burn - not what we earn".

I want that on a bumper sticker.
