Sisyphus as Social Democrat

Brad DeLong's Foreign Affairs review of a biography of John Kenneth Galbraith.

At the beginning of the twenty-first century, it has become clear who John Kenneth Galbraith really is: Sisyphus, constantly pushing the boulder of social-democratic enlightenment up the hill. But the hill, it turns out, is too steep, and Galbraith not mighty enough.

Ah. So if the next Galbraith won't cut it then who will be the next Keynes? Hopefully we won't meet circumstances requiring another one for reasons beyond making the West more politically safe for social democracy.
