The Great War began 100 years ago last week.

From an economic perspective (from Pulitzer Prize economist Liaquat Ahamed) the European nations paid for WWI not with taxes, but with massive debts financed largely by America. The warring nations could not pay their way out of debt so many resorted to the easier route: inflation. But that inflation destroyed the savings of the middle class and that did not make European nations more stable.

Germany finally defaulted on its war debts after the 1929 crash. The international financial system also collapsed. Of course, German people listened to Hitler’s ideas about blame and solutions, while France, half destroyed by the war, looked at Germany (where few battles were fought) and wanted the Germans to pay for that destruction. The Depression made each nation more economically isolated which added to the misery as trade shrank. Europe was ripe for WWII.

WWI could be taken as a lesson on the perils of excessive debt. Governments have discovered three nasty advantages:

They can borrow beyond emergencies (war) to pay for anything.Government pensions (more debt) are excellent ways to buy votes with the vague idea that ‘future growth’ or ‘future generations’ will easily cover the massive pension obligations.Governments have more recently seen that they can lower interest rates and ‘print money’ without being held accountable as they will be bailed out by other countries through central banks which will do, as Mario Draghi famously said, “whatever it takes.” These financial gimmicks look like serious plans because the men wear suits and because their ideas work, at least until the office holders retire.

However, as with WWI debt and the Crash of 1929, a severe crisis e and prove that these leaders (while possibly not as petent or corrupt as the political leaders of Detroit) were wrong.
