In book 1 (chapter 5) of Adam Smith's "Wealth of Nations", it is mentioned that, "...rents which have been reserved in corn have reserved their value much better than those which have been reserved in money - even where the denomination of the coin has not been altered".  This is, presumably, because coin can (and, historically, had been) adulterated, shaved, and otherwise had its value diminished for the purpose of making more precious metal available for the use of the powers that be.  There was no change in the "face value" of the coin, and alterations in its size, weight, and total content of precious metal were only detectable by those with the right equipment (and, indeed, the interest in doing so); more coins could be struck by the sovereign mint, all of which would appear to be of full value to the unsuspecting observer - and the nation would appear to be richer to all engaging in trade with them.

What has happened in our more technologically-advanced age is the debasement of the heretofore stabilizing value of corn.  Corn (indeed all crops, although corn - a generic term for all cereal grains) held a far more stable value because its quality was due to the diligence of the farmers - and because, unlike coin, the value of the farmer's labor would only increase by increasing the output of the corn; if the farmer sought to make his corn more valuable by reducing the number or size of ears per stalk, he would soon fail in his enterprise.

The interference of the government in the field of agriculture, less in regulation and safety practices as in subsidized non-production and GMF (genetically-modified foods), has turned away from the basic wisdom of corn economy - wisdom that was part of the return of a dissolute and ruined Great Britain to the heights of Empire under Elizabeth I.

This attack on the stabilizing "staff" of the economy is unknown in history except in instances of an invading and beseiging enemy force seeking to break the strength of their prey.  By purchasing the souls of those "farmers" who have less interest in the sacred trust of the farmer and more in making and bequeathing fortune as the foolish rich man (Luke 12:16-20), the powers that be wrest control of food from nature and the steward God placed over it.  More monstrous, by taking the "staff of life" that is corn - cereal grains that grow so abundantly of their God-given nature and nourish so well - and altering it so that it grows only where, how, and WHEN those "masters" of the Earth decree, these wicked and selfish servants of evil work the will of the prince of evil to bring mankind to a place of fear and pain.  By limiting the benison of nature to what they mean for men to have, they can control the souls of weaker men with hunger and with pain at seeing their loved ones suffer.

Here we find the meaning behind Revelation 6:6 - "A measure of wheat for (a day's wages), and three measures of barley for (a day's wages)...”
