"Weakness in the U.S. dollar is considered welcome relief by U.S. manufacturers, which have been battered by intense foreign competition as a fall in the greenback would be expected to raise the price of imports and make exports more competitive. In addition, a positive currency translation helps lift revenues and bodes well for the bottom line of U.S. multinational corporations. However, a rapid, destabilizing decline in the dollar may potentially have a negative impact on U.S. equities if capital inflows into the U.S. slow because foreign capital is needed to finance the trade deficit."
Actually, that seems a bit gloomy and doomy to me.
