The major currency which has lost the most value since George Bush became president is the US dollar. The Euro, the Australian dollar, and the Canadian dollar have all strengthened against the US dollar.

I used to get CD $1.50 or better for each US dollar. I now get about CD $1.13 for a US dollar. There has been a dramatic drop in the value of the US dollar in the last few years. Hardly surprising, because the USA is tremendously in debt, building high-tech war materials while others (such as China) make most of the world's consumer goods and earn the proceeds from that accordingly. Building war machines is like dumping your money in a hole in the ground and burning it. They're no good for anything except smashing things up and killing people.

You can't spend more annually on arms and warfare than the next ten countries in the world put together and expect not to go heavily into debt. When you do, your currency loses value...specially if you are simultaneously exporting most of your civilian production overseas wherever labor is cheaper and impoverishing your own domestic work force and middle class in the process.
