Friedman: "In my view, the fundamental conflict is not between bad men and good men but between mistaken beliefs and correct beliefs."
Rothbard: "Granted that life is more pleasant following this tack, but alas, it misses the crucial point. Also, it is unpleasantly reminiscent of the tactic of all ruling classes in history: criticize inflation, but never the inflators; price controls, but never the people doing the controlling, etc. The point is that sins, errors, evils, etc. are not just floating abstractions; they are committed by real persons in the real world, and therefore they cannot be combatted unless people know what is going on in the concrete and who is doing it. Who is inflating and regulating, and for what purpose? It is at that point that we realize that not just abstract error but conscious evil is being perpetrated for the sake of ill-gotten money and power." (From the Jan '81 edition of the Libertarian Forum)
