Where does that leave us today? America’s GDP may have fallen by an annualised 6% in the fourth quarter of 2008, but most economists dismiss the likelihood of a 1930s-style depression or a repeat of Japan in the 1990s, because policymakers are unlikely to repeat the mistakes of the past. In the Great Depression, the Fed let hundreds of banks fail and the money supply shrink by one-third, while the government tried to balance its budget by cutting spending and raising taxes. America’s monetary and fiscal easing this time has been more aggressive than Japan’s in the 1990s.

However, these reassurances come from many of the same economists who said that a nationwide fall in American house prices was impossible and that financial innovation had made the financial system more resilient.

We can be sure if we let the Dems go with their plan of raising taxes and spending trillions on roads that a much longer Depression will come.
