I'm not sure how to phrase this without it sounding like a smart remark, but I truly am just asking.
But in the current economic situation how do you see the feds cheap rates as coming at the expense of the tax payer? Cheap rates are good for anyone that takes a loan, not just banks. Whether it is a business loan or buying a house, it is a great time to take a loan. It is bad for people with lots of savings (cheap rates), but then again, the people that save the most, are the people that have the most and make the most.
Further the main point of cheap rates is to offer incentive to take loans, particularly areas where loans are needed for purchases, such as housing. The housing market is still very weak. One thing a lot of people don't realize is that a strong housing market is almost essential to having any kind of recovery. Historically new housing building accounts for around 5% of GDP, and coming out of most "normal" recessions, the growth in the housing market accounts for around 8% of GDP growth.
