Irrational Exuberance

guardian.co.uk | To most non-Americans, black is still code for being apart from the American establishment. Any visitor these days to Europe, to Africa or to the Muslim world is shocked by the depth of antipathy to the US. It is beyond ideology, a visceral, often racial aversion, unrelated to any personal attachment to individual Americans or their much-envied way of life. The ugly American is reborn.

Yet the same visitor is impressed by how often he is assured that an Obama presidency would "change everything". The reason is not that Obama is anti-war or pro-Palestinian or left or rightwing. It is that his origins render him the one thing he most vociferously denies, not an ordinary American.

To this world, Obama is a supposed representative of an oppressed class, however much his speech, manner and career bespeak the opposite. He is black and his name is confirmation enough. He symbolises the end of the Wasp ascendancy. The reason why his candidacy still discomforts many Americans is the reason the world craves it, that Obama is somehow unreal.

He is a meta-American. It is why there will be an awful unleashing of grief and fury if he is not elected. Yet Obama is real, not just a human being but a politician. In office he knows he must do more than make fine speeches and castigate the government of the day. He must grapple with the wreckage of a world economy whose collapse is in large part due to the mismanagement of American finance, from which as a senator he cannot altogether escape blame.

"Irrational exuberance" is a phrase used by former Federal Reserve Board Chairman Alan Greenspan in a speech given at the American Enterprise Institute during the stock market boom of the 1990s. The phrase was interpreted by financial pundits as a typical extraordinary economy.
