When Larry Summers stood up and called for Negative Interest rates, people were shocked. However, such stunts are all coordinated. This was a trial balloon so that the government can judge the reaction of an idea before its time. Negative Interest Rates are in the cards. So get use to the idea. These people cannot see what they are doing to the economy.
This is like a medieval doctor who bleeds people. It was never that he drained too much blood, but rather that he did not drain the subject soon enough. This is the same thing with interest rates. They cannot grasp that rising rates are normal and this artificial level kills the long-term investment markets.
