I was there thinking...

Prior to the 1980s, conservatives were fiscally conservative— that is, they were unwilling to spend more than they took in in taxes. But Reaganomics introduced the idea that virtually any tax cut would so stimulate growth that the government would end up taking in more revenue in the end (the so-called Laffer curve). In fact, the traditional view was correct: if you cut taxes without cutting spending, you end up with a damaging deficit. Thus the Reagan tax cuts of the 1980s produced a big deficit; the Clinton tax increases of the 1990s produced a surplus; and the Bush tax cuts of the early 21st century produced an even larger deficit. The fact that the American economy grew just as fast in the Clinton years as in the Reagan ones somehow didn't shake the conservative faith in tax cuts as the surefire key to growth.
