Perhaps 'the air of effortless superiority' with which The Mainstream, in which Krugman and DeLong so badly need to remain, habitually employs to dismisses all who cannot trace at least one intellectual ancestor to Samuelson is beginning to seem tiresome. We can hope at least. More likely is that the center and right of The Mainstream will, for the sin of mentioning Keen and other heterodox economists, try to tie Krugman and DeLong to them and also cast them out of Heaven.

As the Dutch said while fighting the Spanish: "It is not necessary to have hope in order to persevere."
