Eva, the "78" awgee is referring to in hiws post is the DX, or US Dollar indeX traded on the New York Board of Trade. It is a collection of currencies valued against the dollar (and vice versa) and is traded as a future, like oil and other commodities. The value of that index can be influenced, shifted, hammered, kited, and cooked by any number of banks, brokers, investment firms, or governments and the President of the United States of America (take that Troop!) can't do a damn thing to stop it. Ask George Soros about his fun with the British pound.
As for deficit spending, if there was a causal relationship, you would see it reflected in the index. In short, the answer is no.
