The actual figure of the US' national debt is much higher than the official sum of $13.4 trillion given by the Congressional Budget Office, according to analysts cited on Sunday by the New York Post. "The Government is lying about the amount of debt. It is engaging in Enron accounting," said Laurence Kotlikoff, an economist at Boston University and co-author of The Coming Generational Storm: What You Need to Know about America's Economic Future. "The problem is we're seeing an explosion in spending," added Andrew Moylan, director of government affairs for the National Taxpayers Union. In 1980, the debt - the accumulated red ink incurred by the Federal Government - was $909 billion.
