We're going to talk about carburetors.
The carburetor is an ancient device used before the days of fuel injection to mix gasoline and air in order to make a car engine run.
Now, when a foolish country boy would run his car completely out of gas, even after he put additional gas in the tank, the car still would not start. First, he was required to splash a little gas in the carburetor and that would provide enough mixture to fire the engine which would then begin drawing fuel from the tank and keep the engine running.
You had to put the gas in the carburetor to make the engine turn over. Putting it anywhere else, say up the tailpipe, was useless.
Keynesian economics states that to get a sluggish economy started again, you have to "prime the pump" or use government spending to stimulate private sector spending. But personally I prefer the carburetor analogy.
Now here's your question. I'm not interested whether you believe in Keynesian theory or not, but, do you think the current "stimulus" package is putting gas in the carburetor or the tail pipe?
