Kevin has to retreat to a war of carefully teased and primped charts and graphs because he doesn't understand basic economics and has literally no critical reasoning abilities such that he could formulate a rational critique of the conservative view to which he is so emotionally averse.
Now, of course, my response is going to be to post chart after chart after chart debunking his own charts and/or his interpretations of them. That's the easy part, and could be accomplished in a short time frame.
The difficult part is just attempting to reach Graham with rational discourse.
Graham's cooked graphs do not impress, any more, as bc pointed out, then have the countless charts and graphs showing unprecedented global warming and how much warmer specific recent cherry picked time periods were then specific cherry picked past time periods.
Graham's tiny smattering of economists as the basis of some kind of overall mainstream view is also just as suspicious as the "consensus" claimed to have existed around AGW, which never existed at all in the manner claimed. He claims that virtually all agree with him, but yet can provide nothing but perhaps a half dozen cherry picked specimens, preferring to argue from authority than from educated principle.
The fundamental principles of economics, historical empirical data, and the principles of what Von Mises termed "praxology", the study of the principles of human action, all coalesce to tell us why, as marginal tax rates and taxes that directly attack risk, investment, and savings (such as capital gains, dividend, and high corporate tax rates) are lowered, tax revenue rises, and why as these rates are raised, revenue falls.
As I mentioned before, this is utterly elementary, logical, and self evident, and there is no reason for me to waste my time cutting and pasting my own charts and graphs demonstrating the empirical history of the matter (its all over the internet, in large quantities, no any who desire to may do their own homework on the subject).
As to the Laffer Curve, I'll let Mr. Laffer defend himself here:
http://www.heritage.org/research/report ... and-futureI should point out here that, while I'm not up to too much cutting and pasting today, as I've done it many times before here while glassy eyed leftists on this board stare uncomprehendingly at the mismatch between their ideology and reality, the above essay contains a thorough and detailed debunking of Mr. Graham's Alice-through-the-looking-glass economic history. Its much more complex than the Keith Olbermann world of polemical fuming and statistics mongering that passes for "thought" in Mr. Graham's world of apostasy and leftist bad conscience.
