Murray Rothbard (whose last name means "red beard") wrote about the role of the court intellectual ('red' or 'raed' is Old English for wise counsel).
"The ruling class — be it warlords, nobles, bureaucrats, feudal landlords, monopoly merchants, or a coalition of several of these groups — must employ intellectuals to convince the majority of the public that its rule is beneficent, inevitable, necessary, and even divine. The leading role of the intellectual throughout history is that of the court intellectual who, in return for a share of, a junior partnership in, the power and pelf offered by the rest of the ruling class, spins the apologias for state rule with which to convince a misguided public." --Conceived in Liberty, Vol. III, p.352
R' Samson Raphael Hirsch wrote about the people who played the role in ancient Egypt-
"In Tanach [the bible] we find, everywhere, Machshefim [illusionists/magicians] in the service of the rulers of old, just as today we find scientists in the service of the state. If today's scientists were to attempt to solve problems such as how one can indulge in every excess and debauchery without having to fear consequences detrimental to one's health - that would be attempting a misuse of man's mastery of nature, and would be in line with the basic outlook of Kishuf. [magic]" --Commentary to the book of Exodus, Chapter 7, Verse 11
This is how you can explain Keynesians who magically believe that you can consume your seed cord into prosperity or otherwise turn stones into bread! Pharoah's scientists had nothing on these goys!
