You what? The lower dollar means everything you get from abroad is more EXPENSIVE!!!!!
This increases your costs! Now go back to economics 101 and concentrate harder ;)!
As everyone keeps pointing out though, the flip side of that is that your goods are cheaper for foreigners which is good for your manufactures whose exports become more competative. (unless they rely on foreign components in which case it is all a double edged sword!)
The cheaper dollar is a shot in the arm for our agricultural exports, and that's a huge help to our economy. As to imported goods costing more, I haven't noticed that cutting into the sale of big plasma TVs this Christmas.
