"The conclusion of [supply side] theory is that a large reduction in U.S. taxes would actually raise government revenues ... Unfortunately, like all other perpetual motion machines, it will not work. It is a lovely vision, but it is actually a mirage - and a dangerous mirage at that." - economics Professor Robert Dunn, in the Washington Post July 9, 1978
