the IMF, those institutional bastions of belief in the free market system, believe that governments should not intervene in the exchange rate, - Karl Polanyi

Where markets were most highly developed, as under the mercantile system, they throve under the control of a centralized administration which fostered autarchy both in the household of the peasantry and in respect to national life. Regulation and markets, in effect, grew up together.

Anthropologically, money should be defined as a semantic system, broadly similar to language; writing, or weights and measures. These systems differ mainly in the purposes served and the signs employed. Language and writing serve the purpose of the communication of ideas, weights and measures that of quantitative physical relationship. As to signs, language uses oral sounds; writing employs ideograms or visual characters; weights and measures, on the other hand, use physical objects as the basis of symbols.
Money resembles, but also differs from, each of these. It serves several ends, which are traditionally described as means of payment; standard of value or money of account; store of wealth; and medium of exchange.

All types of societies are limited by economic factors. Nineteenth century civilization alone was economic in a different and distinctive sense, for it chose to base itself in a motive rarely acknowledged as valid in history of human societies, and certainly never before raised to the level of justification of action and behavior in everyday life, namely, gain. The self-regulating market system was uniquely derived from this principle. The mechanism which the motive gain set in motion was comparable in effectiveness only to the most violent outburst of religious fervor in history. Within a generation the whole human world was subjected to its undiluted influence.
