The Cherished Economic Theories Adopted and Applied Since the 1930s Are Tragically and Fundamentally Incorrect

 The current inflationary depression [1974-1975] has revealed starkly to the nation’s economists that their cherished theories—adopted and applied since the 1930s—are tragically and fundamentally incorrect. For forty years we have been told, in the textbooks, the economic journals, and the pronouncements of our government’s economic advisors, that the government has the tools with which it can easily abolish inflation or recession. We have been told that by juggling fiscal and monetary policy, the government can “fine-tune” the economy to abolish the business cycle and insure permanent prosperity without inflation. Essentially—and stripped of the jargon, the equations, and the graphs—the economic Establishment held all during this period that if the economy is seen to be sliding into recession, the government need only step on the fiscal and monetary gas—to pump in money and spending into the economy—in order to eliminate recession. And, on the contrary, if the economy was becoming inflationary, all the government need do is to step on the fiscal and monetary brake—take money and spending out of the economy—in order to eliminate inflation. In this way, the government’s economic planners would be able to steer the economy on a precise and careful course between the opposing evils of unemployment and recession on the one hand, and inflation on the other. But what can the government do, what does conventional economic theory tell us, if the economy is suffering a severe inflation and depression at the same time? Now can our self-appointed driver, Big Government, step on the gas and on the brake at one and the same time?
