Paul Krugman is planting a very dangerous idea:
If you want to see what it really takes to boot the economy out of a debt trap, look at the large public works program, otherwise known as World War II, that ended the Great Depression. The war didn’t just lead to full employment. It also led to rapidly rising incomes and substantial inflation, all with virtually no borrowing by the private sector.
…
Since nothing like that is on the table, or seems likely to get on the table any time soon, it will take years for families and firms to work off the debt they ran up so blithely. The odds are that the legacy of our time of illusion — our decade at Bernie’s — will be a long, painful slump.
How will people read the above? "Even Krugman says we need another war. Let's start now!"
But was WWII really a 'public works program' that ended the debt trap? Krugman displays a graph at his blog to justify his opinion.
It shows private debt at 240% of GDP in 1932 while public debt was about 40% of GDP. The private debt came down to a 100% of GDP in 1941 while public debt stayed under 50%. When the U.S. entered WWII private debt came down further to 70% of GDP and public debt went up to 110%.
So most of the necessary debt deflation that followed the big debt bubble of the late 1920s had already taken place when the U.S. entered the war. The argument that WWII was a 'public works program' that ended the Great Depression is false.
Most of the necessary healing of U.S. private balance sheets had already taking place before the war started, Simply continuing FDR's civil public works policies for a few more years would likely have had the same result with regards to private debt than the war had.
To characterize WWII as an alternative to a 'long, painful slump' is ludicrous. The years between 1930 and 1941 were certainly already a 'long, painful slump'. The war years were certainly long and painful for those who got wounded, maimed and had to flee from their homes.
What Krugman does in his column is giving people a very bad idea based on very shallow thought.
