I would say that we will collapse Economically before all of these points happen.
The day may not be that far off when the Interest on the National Debt may not be payable.
When Interest Rates move up, whether The Fed likes or not and our other twin evil, Health Care costs, also rise to the point the Federal Budget can’t pay it then our government will collapse.
What will probably happen then is that this country will break up into the different regions and that will be that.
Obamacare will never be insolvent, because the IRS has a claim on all taxpayers income to pay premiums.
