William Niskanen, David Stockman, Stephen Moore, and Bruce Bartlett would all disagree.Well, let me go check out the credentials of these fine, non-partisan economists, and I'll get back to you. (I know who Stockman is, and if Bartlett is from 'Bartlett and Steele', I'll know what you are and I can just laugh and move on.)
Let me save you a little work. Stephen Moore is head of the Club for Growth. Bruce Bartlett is not the Bartlett you're thinking of. He's been in either the Reagan or Bush41 Administration or both. You can find his work at townhall.com or at National Review. And Niskanen was one of the intellectual godfathers of the supply-siders. You can find his work at Cato.
