The dollar is under pressure from everything from economic problems to asset reallocation away from the U.S. and corporate accounting problems. It's difficult to see any positive factor for the dollar at the moment. The root of the problem is the U.S. current account deficit. If the U.S. doesn't have to attract an enormous amount of foreign capital, people wouldn't have to worry about domestic problems. One solution to this is a weaker dollar."
