Greg Mankiw crows that Robert Samuelson has joined the Pigou Club, calling for an energy tax. I would crow because Samuelson writes,

Raise the eligibility ages for Social Security and Medicare gradually to 70 by 2029. At 65, people would have to buy into Medicare (that is, pay for coverage) until they reached eligibility for subsidized benefits.

We need a catchy name for the club of people who endorse raising the age of government dependency. Maybe the Stroke of a Pen club. Other suggestions?
