对战后衰退的分析具有特殊的重要性,因为无论主张哪种学说和属于世界上哪个地区的人们,都想利用这种分析来控制現代資本主义,使其沒有周期性危机而发展到某种程度。約在1957年下半年,大部分輿論界认识到美国行情上升期中断了。各种征象証实衰退已經发生,而且这种衰退是属于一定类型的。 The analysis of the post-war recession is of special importance, for neither the doctrine nor the people belonging to which part of the world want to use this analysis to control modern capitalism to a certain extent without a cyclical crisis . Around the second half of 1957, most of the media realized that the upward spiral of the U.S. market had been interrupted. Various signs confirm that the recession has taken place and that this decline is of a certain type.
