Why the FED's low rates hurting the economy

"Lower rates drive up the cost of commodities: oil and food. And money that is spent on oil is sent out of the country to the Mideast and it doesn't help, and takes out income from people's pockets that could otherwise be spent on other goods. The second [ZH: and this is by far the biggest thing that the Fed refuses to acknowledge] is that not being able to earn a safe return on savings, is causing people to hoard savings rather than consume. In other words if I know I am going to earn 3% in the bank I can spend that income and I can have visibility towards that, but if I know I'm going to earn zero in the bank, in order to figure out how much I need to save for retirement I need to save a much bigger number. Which means I can't spend much now, I need to save more now, to build up those savings for retirement. If I am already retired and I am on fixed income, my income has now really gone down and I have to hoard money so I can spread it out thinner over a longer part of my life. So by denying individuals savings or interest on income on their savings, it is causing hoarding which is driving down consumption which is hurting the economy."
