The US dollar is up for a number of reasons:
permanency in the tax code effective January 1, 2013;
elevated spending by the federal government arrested, due to PARTISAN gridlock (hurrah!);
and increased US DOMESTIC oil production from technology advances, despite the most anti-oil president ever to sit in the Oval.
Just think where we would be if we actually had a pro-US president.
Well, for one thing, we'd be WORKING, most likely.
