What is the connection with the American dream and Of Mice and Men?

The novel "Of Mice and Men" was written at the time of the Depression. When the Wall Street Crash took place, this was when the banks went bankrupt due to stocks and shares and overproduction of goods. Many people were unemployed and had to travel around to look for work (which is what Lennie and George do, they are itinerant workers). Many of these people had an American dream, to have a house, some land, to be famous etc. Curleys wife had an American dream to be "in the pitchers" - to be famous in films. George and Lennie had the dream of owning their own ranch. Crooks had a dream of being treated equally to whites.
