Interest on debt out of control

from the WSJ....the situation is dire. Can there be more bad news?

As of Sept. 30, 2009, the national debt was almost $12 trillion and interest on that debt was $383 billion for the year, according to the Treasury Department's Bureau of the Public Debt. The Congressional Budget Office on Oct. 7 estimated the 2009 budget deficit to be almost $1.4 trillion (about 10% of GDP). In August, the White House Office of Management and Budget (OMB) estimated total government revenues at about $2 trillion. The revenue estimate included $904 billion from individual income taxes. This means the cost of interest on the debt represented more than 40 cents of every dollar that came in from individual income taxes. ...

During Jimmy Carter's years in the White House, Treasury yields reached 15%. The 2009 average interest rate on the debt was only 3.2%. With our mounting national debt and budget deficits, it is reasonable to assume that in the near future interest rates on new and refinanced debt could double or triple.
