Who doomed the presidency of George Bush Sr, and sent him limping back to Houston at the end of his first term? No, it wasn't Saddam Hussein, spared by Bush I in recognition of his long-term utility to the oil industry, on whom Bush Jr, now hopes to inflict revenge.
It was Alan Greenspan, chairman of the Federal Reserve and the man whose wrong-way calls on interest rates at the start of the Nineties ushered in the recession that allowed Bill Clinton to capture the White House on a platform of economic populism.
Guess what? It's happening again! Bush Jr, will learn that you can indeed step in the same river twice, so long as Greenspan is controlling the sluices. Because Greenspan did nothing in the late Nineties to curb the greatest corporate crime spree in the history of capitalism, the Democrats got out of Dodge seconds before the roof finally fell in.
As one economist recently remarked, in terms of economic reality, the late Nineties never happened. Everything was done with smoke, mirrors and crooked accountancy, condoned by Greenspan.
