Most people don't realize that in 1919 the United States was on the verge of revolution-- that on May Day of that year four million working people went on strike in cities and towns throughout the country. There were demonstrations and riots everywhere.
It was an amazing day little covered by America's writers-- except, strangely enough, by F. Scott Fitzgerald in his great story "May Day." Even though he comes at the day from an aspect of privilege, he well captures the turmoil and mood which existed.
His story is also a good example of how the literary art has changed-- become increasingly narrowed. Notice his great opening paragraph which gives context and scope to his story-- making the reader aware that his characters exist WITHIN a civilization; are part of the sweep of history.
Fitzgerald, of course, though not a naturalist himself (though he kind of tried to become one in his second novel, The Beautiful and Damned,) had been influenced by the great naturalists, who at the time he wrote the story were still an enormous influence on our literature.
Compare Fitzgerald's story with the similar one by J.D. Salinger, "A Perfect Day for Bananafish," which borrowed Fitz's ending, to see how the art of the story began changing around 1950, becoming more narcissistic-- a trend which has continued to now.
