The bill of particulars:
U.S. budget is dependent on foreign finance.
U.S. too weak for diplomatic efforts; can now only use force of arms.
U.S. costs out of control to the benefit of the rich only (example—no money for universal health care, but we spend $400 a gallon for gas used by troops in Afghanistan.
U.S. political leadership rife with corruption (example—many on the take from private insurance companies)
etc., etc., etc.
This is a problem because:
In any failed state, the greatest threat to the population comes from the government and the police. That is certainly the situation today in the USA. Americans have no greater enemy than their own government. Washington is controlled by interest groups that enrich themselves at the expense of the American people.
