I had previously calculated what the price of gas was had you used gold as your currency instead of US dollars. The price of oil today would be somewhere around $1.29.
I then figured, "hey, why not convert US GDP in terms of gold?"
I will admit upfront this is not a completely fair comparison in that it is more reflective of the price of gold than it is the productive ability of the US, but it is interesting to note that if we used gold as the currency, GDP today would be a mere $400 billion, about what it was when the last time the economy sucked this bad - Jimmy Carter.
I'm just waiting for the next Ronald Reagan.
