How to become a good Keynesian

R.I.P., six decades after writing the most disastrously influential college textbook in history:

Paul A. Samuelson, the first American Nobel laureate in economics and the foremost academic economist of the 20th century, died Sunday at his home in Belmont, Mass. He was 94.

As Keynes himself famously said, "In the long run, we are all dead." Samuelson has finally become the only good kind of Keynesian, an example we hope Paul Krugman will soon follow.
