WASHINGTON -- A new congressional report released Friday says the United States' long-term fiscal woes are even worse than predicted by President Barack Obama's grim budget submission last month.

The nonpartisan Congressional Budget Office predicts that Obama's budget plans would generate deficits over the upcoming decade that would total $9.8 trillion. That's $1.2 trillion more than predicted by the administration.

The agency says its future-year predictions of tax revenues are more pessimistic than the administration's. That's because CBO projects slightly slower economic growth than the White House.

The deficit picture has turned alarmingly worse since the recession that started at the end of 2007, never dipping below 4 percent of the size of the economy over the next decade. Economists say that deficits of that size are unsustainable and could put upward pressure on interest rates, crowd out private investment in the economy and ultimately erode the nation's standard of living.

Still, the Feb. 1 White House budget plan was a largely stand-pat document that avoided difficult decisions on curbing the unsustainable growth of federal benefit programs like the Medicare health care program for the elderly and Medicaid, which provides health care to the poor and disabled.
