Intellectual error of monumental proportion has been made, and not exclusively by the ordinary politicians. Error also lies squarely with the economists. The academic scribbler of the past who must bear substantial responsibility is Lord Keynes himself, whose ideas were uncritically accepted by American establishment economists. The mounting historical evidence of the effects of these ideas cannot continue to be ignored. Keynesian economics has turned the politicians loose; it has destroyed the effective constraint on politicians' ordinary appetites. Armed with the Keynesian message, politicians can spend and spend without the apparent necessity to tax." ] .source[Buchanan, James M and Richard E Wagner, 1977, [*Democracy in Deficit: The Political Legacy of Lord Keynes*](https://www.econlib.org/library/Buchanan/buchCv8.html)] ] --- # Political Incentives .center[  ] --- # Political Incentives .pull-left[ .center[  ] ] .pull-right[ .center[  ] ] --- # Math Isn't a Partisan Issue .left-column[ .center[  ] ] .right-column[ > "The nation cannot continue to sustain the spending programs and policies of the past with the tax revenues it has been accustomed to paying.
