Update: I see Paul Krugman was already on Herr Steinbrück’s case.
I’m really puzzled by the fears from the German CDU (update: and SDP!) and British Tories about excessive borrowing in the recession. Britain’s current debt-to-GDP ratio is under 50%. In 1815 it was 290%. In the years following the end of the Napoleonic wars, over half the British central government budget went on servicing this debt: £31.1m out of £57.5m in 1820.
Did stagnation or disaster ensue? Not exactly. The next half-century saw Britain’s relentless rise to the first industrial superpower. Of course, with negligible social expenditures, regulation of business, or law enforcement, the country was a libertarian paradise: reeking and crime-infested slums, financial panics, plagues, and in Ireland, famine. But that does not affect the existence proof that a dynamic economy is compatible with much, much higher levels of public debt than anything being considered now.
