I don't understand why zero or negative rate is a "TOTAL DISASTER".
As an individual, don't look a gift horse in the mouth. For the majority of us (65% of the household own their homes) our mortgage payment is now much reduced: From the 8% interest rate of the early/mid 2000 to 3.5% today. If I had a $200K mortgage, my interest saving would have been $9000 per year, more than made up for stagnant inflation adjusted household income of ~$50,000 since the mid 2000. Yes, the saving rate is close to zero but how many of us have significant cash in our bank? It is true that some folks were hurt by the low rates, especially seniors with most of their assets in cash, but for the middle class stable career families, this period is a chance to recover our financial disasters of the Great Recession. Those who do nothing and just complain would have missed a great "get well" opportunity.
Another thing I am puzzled is that economists/government with macro economic policies encourage us to spend vs save saying spend benefits the overall economy even as we go more and more into debt. As individuals it is a disaster in the making especially those who are close to retirement and need saving to sustain their lifestyles. If us individuals ignore those policies, we are better off but the economy suffers.
Right now I think many of us are ignoring those encouragement to spend and spend and spend (I for sure) and perhaps that is why the negative rates do not work.
I am not an economist so there must be something I don't understand or don't know.
