…to balance the humors of the economy:
The Keynesian idea of stimulus has no empirical basis, but the only active tool the government has in a time of economic downturn is its ability to borrow and spend. Surprise, surprise: during the Great Depression, governments fell all over themselves to embrace Keynes’s idea of borrowing and spending to “stimulate” the economy. They did so not because it was proven to work (then or since) but because it justified the one action that would make the government larger and more powerful and the political class larger and more powerful as well.
The Fed is now doing the same thing with inflation “Quantitative Easing”. There is no particular reason to believe that inflating the money supply will produce more real economic activity, indeed the history of the 20th century proves exactly the opposite. However, it is all the Fed can do right now so it is going to grab a convenient theory to justify inflating the currency.
For centuries, doctors tortured and killed their patients because neither they nor their patients had the courage to simply admit that there was little good the doctors could do. They created elaborate and detailed theories to justify their counterproductive interventions. Worse, after a time, everyone, doctors, patients, philosophers, proto-scientists, etc. all came to regard the tool driven rationalizations as facts. Not until the discovery of the germ theory of disease, quantitative chemistry and a general science of diagnostics did the nonsense theory of humors fade away. The invention of new tools drove the development of new, scientific theories.
We are doing the same damn thing with the current economic travails. Rather than admit there is little that the government can do to correct its colossal real-estate screwup, we get to witness the economic equivalent of bleeding and induced vomiting all based on a economic theories that have no other reason for existing that to justify the government bleeding and inducing vomiting in the economy.
“… but it’s what can be done,” could well be one of the most dangerous phrases in the English language. In very many cases, not just economics, the best thing to do is nothing. For any particular bad circumstance, there are near infinite number of actions that can make the circumstance worse but only a very few that can make it better. Indeed, there is no natural law that says that every circumstance can be improved with the capabilities at hand. Sometimes a “can do spirit” backfires. Some circumstances are like earthquakes or tornadoes: you can’t stop them, you just have to ride them out.
Don’t just do something; stand there.
