If you think $4.00 gas is expensive, look at Europe $10.00 per gallon

I was wondering if gas in the US is hovering around $4.00 per gallon, what must be happening in the rest of the world. I checked and the price for gas now in Europe is $9-10 per gallon. So if we think things are hard here in the US, can you imagine diesel trucks at $10 per gallon. This is a global problem, and if it does not get fixed real soon, it won;t be just the US economy that will be going into the tank.
