During the last century and until 1907, the United States had panics, and that, unabashedly, is what they were called. But, by 1907, the language was becoming, like so much else, the servant of economic interest. To minimize the shock to confidence, businessmen and bankers had started to explain that any current economic setback was not really a panic, only a crisis. They were undeterred by the use of this term in a much more ominous context—that of the ultimate capitalist crisis—by Marx. By the 1920's, however, the word crisis had also acquired the fearsome connotation of the event it described. Accordingly, men offered reassurance by explaining that it was not a crisis, only a depression. A very soft word. Then the Great Depression associated the most frightful of economic misfortunes with that term, and economic semanticists now explained that no depression was in prospect, at most only a recession. In the 1950s, when there was a modest setback, economists and public officials were united in denying that it was a recession—only a sidewise movement or a rolling readjustment. Mr. Herbert Stein, the amiable man whose difficult honor it was to serve as the economic voice of Richard Nixon, would have referred to the as a growth correction.
