I share Bill Buckler's concern about exponential debt growth. But one CANNOT compare 1971 dollars to 2010 dollars. The CPI has inflated by a factor of 5.39 times since 1971.

It's still the case, after converting federal debt to constant dollars, that 84% of it has been created since the 1960s. Failing to make this conversion is a form of statistical sensationalism, by writers who are either uninformed (not the case with Bill Buckler, since he refers to the inflation) or simply want to jerk people's chains with arithmetic hockey-stick figures and charts.

Ninety-seven percent of all existing Treasury debt has been created since August 15, 1971!
