For successful management of the economy, one has to go through a complicated and sometimes agonizing process. First, you have to analyze the status quo of the economy correctly.

Is it the continuously declining price level, which no modern economists have assumed in building their economic theories? Or is it the public's worries about the future that are forcing them to save more and spend less? What else? It is no use just labeling the economy as a "deflationary situation."
