How did the social and historical context impact John Steinbeck's writing when he was writing Of Mice and Men?

I'm writing an essay on the novel Of Mice and Men, and for the conclusion I need to 'sum up how the social and historical context would have impacted Steinbeck's writing at that time'.How did the social and historical context impact John Steinbeck's writing when he was writing Of Mice and Men?
Well, I don't know how much this would help, but here's what I do know:





The story itself was set in and written during Depression Era California. People were looking for work in this area, to no avail (in the near future, ';Okies'; would be a crude name for people from OK looking for a far distant better life in California). Futures were uncertain. A sense of ';self'; was hard to obtain. Security was an idea that seemed too lofty to reach.





Steinbeck himself was somewhat of a hobo in the 1920's and also experienced the longing of the ';American Dream,'; like Lenny and George did. His experiences and the experiences of the majority of Americans during the Depression definitely played a huge part in the writing of this novel.
