Yes and do you know why? We are the progenitors of Capitalism with a capital "C". That DEMANDS respect. Not to mention no other currency has a stable a track record as the dollar.
Its simple, because people are already pricing in a US economic collapse. Meanwhile other countries econ troubles havent been priced in nearly as much, so their currency is falling, thus making the US dollar worth more. Not exactly the best way to go about it though I might add.
