>"Throughout the 18th century the National Debt grew and grew, from nothing at the end of the 17th century to about 60 percent of GDP by the end of the War of Spanish Succession in 1715." That's a fifteen-year period, not throughout the 18th century, and for that entire period, England was at war. It's absolutely true: debts help win wars. This isn't surprising: war is one of those times when there's a good argument for borrowing against the future, because the alternative is annihilation. On the other hand, during most periods of peace, historically, debt as a percent of GDP has fallen. http://en.wikipedia.org/wiki/File:US_Federal_Debt_as_Percent_of_GDP_by_President.jpg http://en.wikipedia.org/wiki/File:US_Federal_Debt_as_Percent... The thing is we don't have any more wars worth fighting. Maybe in twenty years the precarious situation of "the largest economy in the world is totalitarian [i.e. China]" will boil over, but that definitely isn't happening any time soon. These days, we just accrue debt for no reason, or to fight a war on nothing (drugs, terror, cancer, tobacco).
