" "The legend of King Midas has been generally misunderstood. Most people think the curse that turned everything the old miser touched into gold, leaving him unable to eat or drink, was a lesson in the perils of avarice. But Midas’s true sin was his failure to understand monetary economics. What the gods were really telling him is that gold is just a metal. If it sometimes seems to be more, that is only because society has found it convenient to use gold as a medium of exchange—a bridge between other, truly desirable, objects. There are other possible mediums of exchange, and it is silly to imagine that this pretty, but only moderately useful, substance has some irreplaceable significance.

Additional quotes by Paul Krugman
I do not mean to say that formal economic analysis is worthless, and that anybody's opinion on economic matters is as good as anyone else's. On the contrary! I am a strong believer in the importance of models, which are to our minds what spear-throwers were to stone age arms: they greatly extend the power and range of our insight. In particular, I have no sympathy for those people who criticize the unrealistic simplifications of model-builders, and imagine that they achieve greater sophistication by avoiding stating their assumptions clearly. The point is to realize that economic models are metaphors, not truth. By all means express your thoughts in models, as pretty as possible (more on that below). But always remember that you may have gotten the metaphor wrong, and that someone else with a different metaphor may be seeing something that you are missing.
No, the problem that the politicians have with the professors is not one of failure to communicate; it is one of failure to say what politicians want (need) to hear, especially when they are trying to seize power from other politicians. And necessity is the mother of invention: a different group, the policy entrepreneurs, has arisen to fill the gap.
