Why Do Intellectuals Oppose Capitalism?
By Robert Nozick: "Wordsmith intellectuals fare well in capitalist society; there they have great freedom to formulate, encounter, and propagate new ideas, to read and discuss them. Their occupational skills are in demand, their income much above average. Why then do they disproportionately oppose capitalism?"
Intellectuals and Socialism
"In 1949, Hayek attributed the dominant position of planning in the West to the role of intellectuals, by which he meant 'professional second-hand dealers in ideas' such as journalists and commentators."

Conspiracy Theories Undermine Liberty
Conspiracy theories are ubiquitous these days, and they range from beliefs on the far left and the far right. However, believing such stories ultimately undermines the principles we hold as classical liberals, says Steven Horwitz, a St. Lawrence University economics professor. He notes that "Our case for freedom must ultimately rest on reason and logic, and we must be open to evidence that genuinely contradicts our understanding of the world."
But besides the logical challenge of classical liberals (or anyone, for that matter) holding conspiracy theory beliefs, such ideas undermine the effectiveness of free markets. "When we fall into conspiracy thinking we are actually accepting the fundamental premise at the heart of every form of socialism: that it is possible for human beings to consciously control the economy or society more generally," says Horwitz. This is not the slippery slope we want to be on.
Obama resorts to Big Brother tactics, erects 'straw men'
Timothy Carney, of the Washington Examiner, recently asked Obama officials who the President was referring to as “opponents” in his health reform speeches. Obama claims that those fighting against his health care reforms are “well-financed” and profit from keeping the system as-is, while has steered clear of naming names. No officials would answer Carney's questions. Carney proposes and refutes several possibilities of his own, but is left with a question: Why might the President and his administration be fostering such unsubstantiated claims? He concludes, "For Obama, a nameless enemy is more useful because it allows people to imagine whatever 'well-financed forces' they like as the enemy." He adds, "It's called demagoguery."
The Foundations of a Free Society
By Nathaniel Branden. "The Soviet Union has invaded and successfully conquered every country on the planet, with one exception: New Zealand. The Soviet Union has chosen not to invade New Zealand. Question: Why? Answer: So we would know the market price of goods."
