Does it make any sense to directly contribute to reducing the US national debt?
No. Unless you are ten Bill Gates rolled into one man, you can not possibly hope to make a dent in the 14 trillion debt. Even if you were and paid off whole debt in one payment, budget deficits would restore it to old glory in a short time. If you have some extra money, I'd advise to either choose a charity and donate to somebody who needs your help directly or if you are so inclined, support a campaign of a financially conservative politician (only if you are sure he is a financial conservative and doesn't just tell this to get elected - I have no idea how you could do it :).
