US debt levels expected to rise to between 200-500% of gdp......

Up from the current 60% of GDP. Much of the increase in debt comes from retirement and healthcare obligations promised by the government but unfunded and to only be paid for out of future tax revenues or taxes. Can someone say 'Ponzi scheme'.....

Argentina has a long history of deficit spending, which, in turn, has made government debt burdens so high that the government refuses to pay the debt to the private domestic and international debt holders. Over the next 30 years, economists associated with the Bank for International Settlements in Basel, Switzerland, estimate (as have many U.S. economists) that the U.S. public debt will rise to between 200 percent and 500 percent of GDP. (It is now about 60 percent.) Debt levels of 200 percent to 500 percent cannot be supported; hence, the debt holders will face erosion of their capital through either inflation or nonpayment.

The U.S. is not yet Argentina, but, if many of the policies of the Obama administration are not reversed, America will only get poorer and, in as little as 30 years, become a middle-income country, while dozens of other countries will enjoy a higher standard of living.

But there are other disturbing comparisons to failing states as written here.
