One more question if you feel like keeping this going-I have never understood why China, Japan and other nations need to buy US treasuries in the first place? Like, why does a country have to put their excess money, money that I'm assuming they made over the last year in trade, anywhere? Why do they buy US treasuries, why not just put their money in the Chinese central bank or something? I know China and Japan both know that Washington is devaluing the dollar so why do they keep purchasing our debt? Why purchase anything?
