I think the real problem is that the media does not challenge this factual assertion whenever Republicans recite this talking point. If President Obama appears on Fox News, he can't get in a word over the host's recitation of talking points. But, if Donald Trump says that President Obama was not born in the United States, the interviewer sits there and smiles politely. Thanks to the corporate media propaganda machine, the myth of Reagan continues to live, and woe to the interviewee who tries to assert otherwise.

Here's Rep. Joe Walsh, (R-Ill.) the self-styled "conservative Tea Party activist" who upset Democrat Melissa Bean in the 2010 midterms, on ABC's "This Week."
"In the '80s, federal revenues went up," said Walsh. "We didn't cut spending. Revenues went up in the '80s. Every time we've cut taxes, revenues have gone up. The economy has grown."
If you look at the raw numbers of federal tax revenue over the last 40 years, you will notice a striking phenomenon -- the numbers almost always go up, except in the case of deep recessions. This is basically a function of population growth, and it happens whether taxes are cut, or raised.
But the raw totals don't tell you much, because of inflation. In 2006, Time business columnist Justin Fox adjusted the raw federal tax income revenue totals for inflation, and discovered an interesting thing. Revenue fell in the first few years after both Reagan and Bush's tax cuts, before growth resumed. In 2008, Paul Krugman adjusted for both inflation and population growth, to try to figure out the per-capita tax revenue increase for each decade since Reagan, and found something even more enlightening. Real revenues per capita rose 19 percent from 1980-1988. From 1992-2000, real revenues per capita rose 41 percent -- after tax hikes by both George H. W. Bush and Bill Clinton! And the numbers for George W. Bush? Pure disaster.
Of course, George Bush's term ended in economic Armageddon, which always plays hell with statistics. The rise and fall of the business cycle needs to be taken into account when comparatively judging revenue increases or decreases. But the consensus view of most of the economists who have attempted to sort this out is that in general, tax cuts do not pay for themselves by increasing revenue -- unless you are moving down from an extremely high tax bracket.
