Something that I think a lot of people at least in America don't really understand. is how much USD is circulating around the world. For instance, I'm in Panama right now and the entire country runs on dollars. It's the official currency. Other countries like Uruguay have their own currency but a gigantic portion of the economy is in dollars. This amount of money floating around internationally is a huge risk to the USA domestic economy. It makes it even more important to protect the value of the dollar so as to keep that money outside of the United States.
