America is digging itself into a deep fiscal hole. In 2009, the federal government spent $3.5 trillion, but took in only $2.1 trillion in revenue — thus spending $1.67 for every dollar it collected. The resulting $1.4 trillion deficit was equivalent to 10% of the nation's economic output, the highest percentage since the end of World War II. America's publicly held debt now totals $7.5 trillion, about 53% of gross domestic product — the highest it has been in more than 50 years.
