Debt and morality. From an interview in Die Zeit.
ZEIT: But shouldn’t they repay their debts?
Piketty: My book recounts the history of income and wealth, including that of nations. What struck me while I was writing is that Germany is really the single best example of a country that, throughout its history, has never repaid its external debt. Neither after the First nor the Second World War. However, it has frequently made other nations pay up, such as after the Franco-Prussian War of 1870, when it demanded massive reparations from France and indeed received them. The French state suffered for decades under this debt. The history of public debt is full of irony. It rarely follows our ideas of order and justice.
ZEIT: But surely we can’t draw the conclusion that we can do no better today?
Piketty: When I hear the Germans say that they maintain a very moral stance about debt and strongly believe that debts must be repaid, then I think: what a huge joke! Germany is the country that has never repaid its debts. It has no standing to lecture other nations.
ZEIT: Are you trying to depict states that don’t pay back their debts as winners?
Piketty: Germany is just such a state. But wait: history shows us two ways for an indebted state to leave delinquency. One was demonstrated by the British Empire in the 19th century after its expensive wars with Napoleon. It is the slow method that is now being recommended to Greece. The Empire repaid its debts through strict budgetary discipline. This worked, but it took an extremely long time. For over 100 years, the British gave up two to three percent of their economy to repay its debts, which was more than they spent on schools and education. That didn’t have to happen, and it shouldn’t happen today. The second method is much faster. Germany proved it in the 20th century. Essentially, it consists of three components: inflation, a special tax on private wealth, and debt relief.
