'Perhaps the greatest achievement of market economies is in economizing on the amount of knowledge needed to produce a given economic result. That is also their greatest political vulnerability. The public can get the economic benefits of such systems by judging results without understanding processes. But in their political behavior, the public must judge processes - including economic processes of which they may be ignorant or misinformed. Public misunderstandings can lead not only to misinterpretations of economic benefit as harm, but to actual harm resulting from policies designed to “correct” perceived problems. Once the process is underway, every perceived problem - whatever its reality or origin - calls for political solution, and these “solutions” tend to create a never-ending supply of new problems to be “solved”.'
