So says Robert Higgs, here:
Given that the Fed’s official policy is to drive all interest rates to near zero, one may conclude that the Fed seeks to impoverish the widows, orphans, retired people, and all other financially untutored people who rely on interest earnings to support themselves in their old age or adversity. Can a crueller official policy be imagined, short of grinding up these unfortunate souls to make pet food or fertilizer?
The politicians constantly bark about their solicitude for those who are helpless and in difficulty through no fault of their own. Yet, the scores of millions of people who saved money to support themselves in old age now find themselves progressively robbed by the very officials who purport to be their protectors.
