Cain:

“Why doesn’t economic stimulus work? When it comes in the form of federal spending, it doesn’t work because it’s based on a completely wrong notion of what spurs prosperity. In that respect, it’s much like a drug.
Consider the effects that a stimulant like caffeine has on your body, or even a stronger stimulant like amphetamines. These stimulants merely provide a very temporary boost to your energy – keeping you awake when you should probably be sleeping, or keeping you operating at a high level when you need rest. They make the body act in an unnatural way, and that doesn’t come without consequences.”

Sorta like the GI Bill was such a failure.
