Who destroyed U.S. economy ? USA overall debt today is 367% of domestic product

"How my G.O.P. destroyed the U.S. economy." Yes, that is exactly what David Stockman, President Ronald Reagan's director of the Office of Management and Budget, wrote in a recent New York Times op-ed piece, "Four Deformations of the Apocalypse."

Briefly , in the past 40 years Republican ideology has gone from solid principles to hype and slogans.
Example? Stockman says "the second unhappy change in the American economy has been the extraordinary growth of our public debt. In 1970 it was just 40% of gross domestic product, or about $425 billion. When it reaches $18 trillion, it will be 40 times greater than in 1970." Using inflation factor of 4,6 time in that period that means today debt should be today 1960 billions. But it is 9,18 times higher. 4/10 x 9,18 give today's USA debt 367% of domestic product


National debt of Greece, put at €300 billion ($413.6 billion), is bigger than the country's economy, with some estimates predicting it will reach 120 percent of gross domestic product in 2010.

Now who is  worse debtor,  USA 367% or Greece 120% ?  USA of course, three times worse.
 Obviously we have 271% of USA external debts translated to internal, according to table below. Only 4 countries ( in bold  below) unable to do it are worse than USA (UK is debt holder thus it is only relative debtor). Thus , in absolutely terms worse debtor than USA are only Ireland, Netherland and Switzerland.
