Government Deficit 2008: Many countries are struggling with a national debt that surpasses their gross domestic product. As seen on this list, with a GDP of 54.6, the United States government deficit is better than Greece, the highest debtor that has a national debt of 114.8 GDP. But this is nothing compared to the role model Estonia that has a government deficit that is only 4.1 percent of its gross domestic product(2009). Debt is defined as the entire stock of direct government fixed-term contractual obligations to others outstanding on a particular date.
