The real reason intellectual conservatism is on life support is that the Republican Revolution and their Great Experiment failed. Medicare is so mainstream that Teabaggers shout, "Keep the government out of my Medicare!" John McCain rails against Social Security while quietly collecting his checks monthly.
Social security, Medicare and the federal school lunch program succeeded. Roosevelt's heavy regulation of the financial markets succceeded until dismantled by the Republican Revolution.
Conservatives now have fallen back on Gore Vidal's "Socialism For rich; capitalism For poor!" and Nouriel Roubini "Gains privatized & losses socialized." Dean Baker in his book, "The Conservative Nanny State," debunks the myth that conservatives favor the market over government intervention. In fact, conservatives rely on a range of “nanny state” policies that ensure the rich get richer while leaving most Americans worse off. Corporate welfare has been maintained while other welfare programs have been pared. Conservatives have used the government to distribute income upward to higher paid workers, business owners and investors.
http://www.conservativenannystate.org/cnswebbook.pdfDuring the glory days of the conservative movement, from its ascent in the 1960s and '70s to its success in Ronald Reagan's era, there was a balance between the intellectuals, such as Buckley and Milton Friedman, and the activists, such as Phyllis Schlafly and Paul Weyrich, the leader of the New Right. The conservative political movement, for all its infighting, has always drawn deeply from the conservative intellectual movement, and this mix of populism and elitism troubled neither side.
Today, however, the conservative movement has been thrown off balance, with the populists dominating and the intellectuals retreating and struggling to come up with new ideas. The leading conservative figures of our time are now drawn from mass media, from talk radio and cable news. We've traded in Buckley for Beck, Kristol for Coulter, and conservatism has been reduced to sound bites.
The brain waves of the American right continue to be erratic, when they are not flat-lining. ...the "birthers" have become the "grassy knollers" of the right; their obsession with Obama's origins is reviving frivolous paranoia as the face of conservatism. (Does anyone really think that if evidence existed of Obama's putative foreign birth, Hillary Rodham Clinton wouldn't have found it 18 months ago?)...The right has always produced, and always will produce, potboilers. Conspicuously missing, however, are the intellectual works...But some on the right think talk radio, especially, has dumbed down the movement, that there is plenty of sloganeering but not much thought, that the blend of entertainment and politics is too outre. John Derbyshire, author of a forthcoming book about conservatism's future, "We are Doomed," calls our present condition "Happy Meal Conservatism, cheap, childish and familiar."...
But Tanenhaus is right to direct our attention to the imbalance between the right's thinkers and doers. The single largest defect of modern conservatism, in my mind, is its insufficient ability to challenge liberalism at the intellectual level, in particular over the meaning and nature of progress. In response to the left's belief in political solutions for everything, the right must do better than merely invoking "markets" and "liberty."
Is Conservatism Brain-Dead?
