I suppose that’s one way to look at it: Keynesian economics as a make-work project for anti-Keynesians. On the other hand, if the notion that digging holes to fill them in again doesn’t strike you as the epitome of an insane economic policy then what hope is there for any of us other than for the hole-digging and hole-filling industries, along with businesses in shovel and overalls production. But Alex does get the nature of Keynesian economics 100% right. It is just what Keynes recommended and Krugman to this day supports.
