Interest Rates on a Downtrend

It never ceases to amaze me that anyone is willing to accept such paltry interest rates as the prices of treasuries continue to rise (interest rates and bond prices move inversely to each other), but such is the case. Don't they realize that they are losing money to inflation by buying these things? There is no end in sight to lower rates according to this trend. Perhaps one reason for this is that treasury futures purchases are also a barometer of fear. When people buy treasuries, they are often doing it for fear of losing their money by investing it anywhere else.
