Pat Gunning wrote that "The German "economy" of the period is hardly the
kind of economy about which Keynes and the Keynesians were writing."

In the preface to the German edition of the General Theory (September
1936), Keynes claimed that his theory was "much more easily adapted to
the conditions of a totalitarian state [totaler Staat]" than the
classical theory was.  This justified him in calling it a "general
theory" which "remains applicable to situations in which national
leadership [staatliche Fuehrung] is more pronounced".
