Last Sunday, Fareed Zakaria (above) did an instructive comparison between the economies of the US and the EU in the aftermath of the Subprime Mortgage Crisis. The histories of the two economies are different: the US followed an expansionary fiscal and monetary policy while the EU embraced austerity. Expansionary economic policy involves decreasing interest rates, increasing government spending and increasing the deficit. Austerity involves fighting (imaginary) inflation, reducing government spending and decreasing deficits. As far as historical experiments go, the results are pretty clear. The US is forecast to grow modestly next year while the EU is forecast to contract.
These lessons of history are hard for the right wing to understand: expansion means growth and austerity means contraction. The presumptive Republican presidential candidate, Mitt Romney, has been preaching austerity for the US as the correct response to the Financial Crisis (here). The Tea Party movement is also preaching austerity (for example, Rick Santelli of CNBC and Senator Ron Johnson, R-WI). Their arguments are based on Rick Santorum's Old Time Religion: when you've been profligate, you need to repent. Their arguments are just not based on history as it is unfolding or did unfold during the Great Depression of the 1930's.
