As John Locke wrote in his essay "Some Considerations of the Consequences of the Lowering of Interest and the Raising the Value of Money" in 1691:
"This business of Money and Coinage is by some Men, and amongst them some very Ingenious Persons, thought a great Mystery, and very hard to be understood. Not that truly in it self it is so: But because interessed People that treat of it, wrap up the Secret they make advantage of in mystical, obscure, and unintelligible ways of Talking; Which Men, from a preconceiv'd opinion of the difficulty of the subject, taking for Sense, in a matter not easie to be penetrated, but by the Men of Art, let pass for Current without Examination. Whereas, would they look into those Discourses, enquire what meaning their Words have, they would find, for the most part, either their Positions to be false; their Deductions to be wrong; or (which often happens) their words to have no distinct meaning at all. Where none of these be, there their plain, true, honest Sense, would prove very easie and intelligible, if express'd in ordinary and direct Language."
The modern equivalent of that statement is: "Those who know how to make money will keep it a secret and confuse those who do not know how to make money with bull shit." Which is basically what I was getting at in my previous post.
