"It is no crime to be ignorant of economics, which is, after all, a specialized discipline and one that most people consider to be a 'dismal science.' But it is totally irresponsible to have a loud and vociferous opinion on economic subjects while remaining in this state of ignorance."
~ Murray Newton Rothbard

Rothbard says it like it is. Once I'm done reading Mises, I may have to check out some of this guy's work.
