Slow recovery

According to many experts the slow economic recovery is caused by businesses not investing. They are sitting on cash waiting for some long term plan for tax reform and for Obamacare to be fully implemented and finally concern over new regulations. I believe there is another factor that many overlook. My entire adult life the government has spent more than it has taken in and for the most part there have been no discernable adverse effects but that is changing. There is evidence showing that when the government debt, (federal, state and local) reaches 90% of GDP that the economy begins to suffer in a noticeable manner. We are now at 84% and rising. This might well be one of the reasons why we are experiencing the slowest recovery since the depression.
