Society established gold and silver as a circulating medium and as a legal tender in order that exchanges of commodities might be facilitated; but society blundered in so doing; for, by this very act, it gave to a certain class of men the power of saying what exchanges shall, and what exchanges shall not, be facilitated by means of this very circulating medium. The monopolizers of othe precious metals have an undue power over the community: they can say whether money shall, or shall not, be permitted to exercise its legitimate functions.
