National Debt by President: LBJ to Obama

NEW YORK (TheStreet) -- As Americans prepared to ring in the new year, their government was ringing up its largest national debt in history.

On Dec. 31, 2010, the U.S. public debt passed $14,000,000,000,000 (that's $14 trillion).

For the average American earning an annual salary of $32,048, the number might be hard to fathom.

The combined market capitalization of America's 10 largest companies: Exxon Mobil(XOM), Apple(AAPL), Microsoft(MSFT), Berkshire Hathaway(BRK.A), GE(GE), Wal-Mart(WMT), Google(GOOG), Chevron(CVX), Procter & Gamble(PG), and IBM(IBM) is $2.25 trillion.

In the coming weeks, America will again bump against the $14.3 trillion debt-ceiling last approved by congressional bill H.J.RES.45, signed into law by President Obama on Feb. 12, 2010.

White House Council of Economic Advisers Chairman Austan Goolsbee warns that a failure to raise the debt-ceiling is "essentially defaulting on our obligations, which is totally unprecedented in American history. ... The impact on the economy would be catastrophic."

Not everyone agrees.

In an interview with The Gold Report, Doug Casey, chairman of Casey Research, argues that "once the U.S. government defaults on its debt, people will think twice before lending it any more money; giving politicians the ability to borrow is like giving a teenager a bottle of whiskey and the keys to a Corvette ... the debt is an albatross around the necks of the next several generations; it's criminal to make indentured servants out of people who aren't even born yet."

Adding to the national debt is more than $100 trillion in estimated future costs associated with Social Security, Medicare, prescription drug benefits and the liabilities of government-sponsored enterprises, Fannie Mae and Freddie Mac. A 21-year old taxpayer entering the workforce can anticipate a personal obligation of approximately $1.1 million.

Since 1964, the U.S. debt had accelerated fastest under President Ronald Reagan, at an annualized growth rate of 14.18% -- a record held until Jan. 20, 2009. Following the inauguration of President Obama, the national debt has grown at an annualized rate of 15.21% -- a statistic that might give Democratic leadership pause ahead of an imminent debt-ceiling vote.
