"I notice from Niall Fergusson's long piece on the financial crisis in Vanity Fair that since 1957, when the US Dollar was adorned with the motto "In God we trust", its value has fallen by 87% relative to the consumer price index. This is no more than a measure of inflation, I know. But it is still a fun statistic."
