Low interest rates may be counterproductive. People that are saving for education expenses have to save more, people who are saving for a downpayment for a house have to save more, people saving for retirement have to save more and retired people have lowered incomes. If interest rates were to start moving up people sitting on downpayments waiting for home prices to drop further might start buying homes which might stabilize home prices or even increase their value thereby making homeowners feel more wealthy.
