Sorry for the delay as away most of day.
Knife in Back reference means there supposedly in a Black Cloud moving in on the Investing World due to tremendous debt.
Or, as we would refer to it, the Stock Market in shambles and the value of homes dropping precipitously in levels that will cause panic as owners experience .
When it will all come about.. who knows..but the Economist says it will. So when you get that feeling of deterioration or, a knife in the back.. be ready with a plan to protect your assets, family and friends as best you can.
Like I said, I hope this Morose Prediction holds off so that it is not in our time.
