The Younger family aspires to move out of their cramped and worn apartment. George and Lennie share a dream of property ownership and inspire Candy and, for a time, Crooks to join them in dreaming this dream. In each story, the idea of physical mobility is associated with social mobility.
The notion of home ownership for Lena Younger is one of improvement and betterment. This is also true, materially speaking, of Lennie and George as they consider the idea of buying a piece of property of their own.
In each story, the idea of moving up in the world via property ownership is repeated numerous times, becoming a goal and a refrain. One major difference between the stories, however, comes in the reality of this notion. The Younger family achieves this dream while George and Lennie have little initial chance of reaching their goal. In the end, Lennie dies before he has a chance to tend any rabbits.
