This Sunday's Times magazine contains an article about Barack Obama that is arguably more interesting for its historical scope.
It provides an overview of where the nation has been and seems to be heading in terms of typical economic well-being, government policies, and the interaction between the two. I'm not sure I believe the author's assertion that Obama's emerging economic policy perspective is both more liberal and more conservative than his predecessors', depending on how you look at it. Rather, I think it is a synthesis of what we have learned about the macroeconomic impacts of policies, not unlike a prevailing view in any field of study.
